Ultimate Racing Catback w/ Ebay Downpipe
 

Thinking about ordering up my ebay catless DP. Just wanted some feedback on overall loudness and highway cruising at 3k inside the cabin. More specifically, I'm interested in hearing an opinion of someone who might have had the CBE before the DP and knows the difference.

I make pretty good power on my current setup, especially with corn, but I wouldn't mind more power and I love the raw sound of a MS3 with a downpipe. I guess this is to feed more of my ricer side that wants that sound, versus the performance. Though, I'm not gonna be mad at added performance. :) I just want to make sure the DP is a good addition, not one I will regret, being that the UR has 0 resonators.

Anyone?

I have a UR TBE (with a cat), and it's honestly not loud enough for me. Catless would make it a little louder, maybe "dronier", but I really don't have any drone at 3k.

I have the knock off obx running catless cp-e. I can honestly tell you mine is loud as crap compared to cbe and test pipe. I like it though.

Heh, I'll order a DP and we can trade. :flowers1:

I would like to do full UR with or without the cat, but its pretty pricey and out of my budget. And the next step up is CNT catless which was about $220-240.

Ive got the ebay dp and a ur abe and its quite loud, even with the stock mid pipe. But i love the sound.

The ebay DP quality and fitment were okay? I've had terrible luck with ebay exhaust parts. LOL. Did you get the M2 or speeddaddy?

Ask @Captain KR; about fitment, he swears off them

I've heard only good things, but only from people who don't actually have one. LOL.

I'm running the ur catback with a catless dp car sounds great


I have helped install a couple eBay dps they fit nicely

I have the CNT Catless DP and had no fitment issues at all. I still have stock mid pipe and axle back and it has a nice sound but would like it a little louder. I'm thinking of have a shop do straight pipe from the axle back with some decent tips but for a little more you can get the Speed Daddy, CNT or OBX cat back but from what I have read, most of those have had some minor fitment issues.

Cold starts on your car are ridiculously loud though lol

Great fitment, the only thing i had to bend was the hangers. KOSpeed was the brand. Quality piece for the money.

It wasn't that bad before the bt swap tho.

Just buy the catless ebay pipe alex....b/c Racecar!

wtf you talking about @rwelsh; i love ebay parts

That's what I was saying ninja

I drive bout 30 miles a day to go to work and I have a ur catless dp with the ur catless test pipe matched up to a magnaflow cbe and the sound is good imo no drowning in my car at all if you want to hear the turbo sing you still can.

@GunGuru727; catted UR TBE. Loud as fuck on cold start, great sound through acceleration, can't speak to 3k highway drone, but he can help you out.

I did have the UR CBE before I put on the high flow downpipe they make. I honestly could not tell much of a difference in sound. Just a tad throatier around town. Nothing to worry about if noise is a problem. Cold starts are loud as shit with pretty much any aftermarket exhaust for these cars with the exception of the Magnaflow.

I have also heard the UR catless set up as well...its just a different sound, not much louder to be honest. I think UR does a great job with their mufflers which will drown out most of the twangyness of a full catless set up..exp OBX.

Drone was also not a problem for me either - add all motor mounts and it does add to the whole sensation but its not bad at all...I drive my car everyday and I drive A LOT. Very manageable. Not once has my woman said that it was too loud or annoying. Even if so I would say STFU biatch. lol

Let me know what you do man. I just sold my entire set up actually. Selling the car.

I have the stock catback and a res. delete with an ebay catless... fitment is great! Great part and im very happy with it overall. I did take the extra time to weld an extra bead in the bellmouth to smooth the transition just for added security and hopefully less turbulence.

@CWP_MS3; I'm going the exact same route. I'm leaning towards the SpeedDaddy, there's a couple NJ guys running the ebay DP and love them.

I'm in the same boat though, I know there's more power to be had going with a bigger intake on the K04, but, I want that throaty sound :D

Running cat less requires raising the idle thru ap to avoid smoking k04. How do you guys go about that and how hard is it to raise the idle?. I heard ebay dp are legit, since I'm not the only one with being on a budget on this forum. I would like to save some money for some internals.

Internals first, then downpipe.... no other way to it.


No need to raise the idle unless your turbo is already smoking. If you go catless and find that it is smoking you simply raise the idle via accessport or you can get a bnoon banjo bolt to restrict oil flow a little.

No doubt, def internals first no if's and buts around that. I was just little iffy about running catless about hearing the turbos smoking. But you clearly sum it up.

Downpipe...... Ordered.

UR Catless Exhaust...
 

Safe to say you'll have it on for MNM? I'm looking forward to hearing what mine will sound like


tappy, tap tap taparoo.

Which one did you get?

UR Catless Exhaust...
 

CWP_MS3; I ordered the ATP DP, for 268 bucks shipped (similar to cnt)


Tippy tapay mothafuckas

I should. Hopefully tuned for as well.

I ordered the speed daddy since the m2 and some of the others that were slightly more expensive all look the same to me.

Well, I will get video up of the sound difference between stock cats and catless for those who wonder the same in the future.

Yes keep us updated, exhaust upgrades are certainly in my future.

Going catless does not cause the Turbo to smoke. It just makes the problem known. The cat will actually hide the smoke until it becomes worse. By going catless, you have no cat to filter that smoke, so you will notice it right away.

If you go catless and notice smoke, stock out and tell the dealer you notice a lot of thick smoke coming out of your exhaust after long trips. It is a known problem with this platform, so you shouldn't have much of a problem if your turbo does begin to smoke.


Also on a side note, is anyone running the Cp-e Triton catless?

@dantes5823; had the catless triton and the shit was loud as fuck. He traded it for a corksport one or some shit.

I'm running the UR one catless with a resonator and its loud as hell. Louder than my speed daddy shit I had few months back that I cut the resonator off of. I'd sell that shit too but I had to extend it and go vband so I'm stuck with it.

Here's my videos on the difference. Just doing the dp didn't seem to add the drone for me but when I switched to a new cbe it got loud. The dp quality wasn't too bad but if I had to do it again I would order a different cbe.

Stock cbe with speed daddy dp

Full speed daddy tbe. It had some harshness when I let off the gas on the video but its gotten quieter since then somehow.

Ziggity,

What's your rsb setting on?

Middle setting

DP should be in tomorrow, and hopefully installed by the end of the week. :) And then YT video!

When mine came in the mail it also came with bolts instead of studs. Boy was that a train wreck... I ended up ordering studs from edge since those bolts have been known to back themselves out on their own.

I have the UR Catted TBE and the sound, fitment, quality is awesome and if your worried about the cold start just hold the gas slightly while starting and the car will idle down and be much quieter (thank you Johnathan Rice Kang) for that awesome tip.

@CWP_MS3; i had the UR TBE system for a year. All i can say is it sounds awesome and aggressive compared to magnaflow. It does drone a bit but i'm 19 so doesn't bother me. Took the car on a 1000 km trip fully bolted and my ears were still fine so hope that helps

Just installed my catless M2 eBay DP 2 weekends ago, and I've had to get a new in stream O2 bung welded in (gen 2) and also the DP was about 3/4" too short. I ended up just manhandling them together, but there was a lot of resistence. I had the stock CBE extended so it would take the strain off the DP. All is perfect now, and with the Stock CBE, I think it sounds just right. Aggressive under medium/WOT, but not drone-y cruising. I know not aftermarkert CBE, but more data for you.

That's the 2nd complaint I've heard of the ebay DP's being too short. Kind of interesting because some people have had zero issues with their fitment or welds. I guess when they're made cheapy in china 0 fucks given to every one of them being perfect.
@RLam; Why did you have to get another bung welded in?

With the downstream O2 being installed in the extended bung, it gave me P2096, 0137, and 0139. AFRs were at ~14 at idle. Gen 2 apparently cant use the extended bung. After the new bung, everything is great and no CELs after 500 miles

Oh, and the car runs like a raped ape now.

Mine was pretty much identical, short and had to have a standard o2 welded in. Otherwise its been fine.

How much was it to get the bung welded?

I'm lazy, I want plug and play, I'm gonna go ATP.


tappy, tap tap taparoo.

Well, these are a few issues, but there are others running these without issue. I'm hoping I am one of the lucky ones.

Welcome to china?

I had 2 seperate trips to get the pipe extended and bung welded. It was $102 total with each being ~$50

Even with the extra $100 i'm still happy. If I would have bought the UR DP, It would have been about the same with the adapter for the stock CBE

Shit, its still a LOT cheaper than a UR DP. Don't forget you have to buy the TP separate. Only one comparable would be the ATP, which is about 290 IIRC.

I made mine work without any extension, and I believe the bung weld job was 30-40 bucks. So i was still under 200 bucks all in.

I just got a Speed Daddy from a friend. He has a Pu too, and has already had a new, closer, shorter bung welded in. Some cracks on the welds have developed, but I got a guys that's going to TIG weld over everything again for free. Cost me $50 total ($50 for the pipe, free welding) :D

I had the same codes. Rob removed them for me.

What codes? Some of them you can't just "remove"

I have the UR V1 ceramic and I just got the p2096 code for the second time yesterday. My AFRs are anywhere between 14.2-14.8 when idling.

@MS3inDC;

Alright, so this was taken with a cell phone so it doesn't sound loud, but this exhaust really isn't quite. The ultimate racing catback is a tamed beast - best way I can put it.

Stock Cats Cold start:

As far as the Ebay DP is concerned:

Fitment was just fine, outside of the usual pain in the ass installing a downpipe is. They give you bolts instead of studs, I just reused the stock hardware, minus 1 nut that got a little messed up when pulling it off. It was reuseable, I opted for a new nut. It could use to be like a 1/2inch or so longer, because it pulls my CBE forward, but it wasn't like it came up short and I'm running open DP because I couldn't make it work. Could they make it longer for perfect fitment? Yes. Does the length I got have a dramatic impact? No.

No CEL's yet, but that may change after a couple cycles, so far it has seen about 3. I'll keep that up to date if I get any soon. I expect to.

Driving, its really not that bad. Its aggressive, and its definitely louder, but IMO its not obnoxious. Its definitely a blast to pass people who are going slow, knowing you're going to rattle their entire car as you go by. :)

Drone... Not really bad at all. The only time it really gets loud, deep and kind of obnoxious is when you're engine braking. Higher the RPM the louder and more annoying it is. It may not bother some, I'm kind of picky. With that being said, its not enough to make me want to pull the exhaust off.

Overall, I'm really happy with the Ebay DP and the sound of my exhaust now. And I'm happy that I could use the ebay DP and save myself some money.

that sounds like pure sex , i like .

Yeah, the wife isn't overly fond of it, but you can dumb it down a bit if you shift early. I'm not going to lie, its pretty fucking loud. I kind of retract my statement earlier, now that I'm driving it more. Lol. I'm not upset with my decision at all, but I did consider 1 resonator. We'll see, its to early to tell if it will bug me.

Too loud is just loud enough.


tappy, tap tap taparoo.

Your bumper is a dirty whore just like you @CWP_MS3; but seriously it sounds good. I was just afraid to go with an eBay DP because I don't want to weld a new bung in and all that shit so I am just going to spend a little extra and get a corksport that way i KNOW it will fit my corksport TP fine as well as not have an extended bung.

I just picked up a UR CBE off of a friend and I'm running Catless TurboXS DP/TP.

He was running a stock DP/TP and it was too loud for him so he put in a Magnaflow resonator. So I'm hoping it isn't too loud on my car. We shall see soon...

Well now its been through 7 key cycles and still hasn't thrown a code. Outside of the fact the inner part of the flange looked sloppy, the rest of the welds were sexy beads. I was skeptical as fuck, but so far so good.

Like I said, it could have used to be a little longer. Given my CBE is a 3inch it was close to rubbing a heat shield because it was pulled closer to the front. If it was a stock CBE, that wouldn't be an issue. The UR mid pipe is fucking huge compared to stock.

No way. UR with stock cats is still sexy as fuck, and not ungodly loud at all. It was perfect for me, and I had a metric fuck ton of mental debate over whether or not I wanted to add a DP to it, for fear it would make it too loud.

Just took 2 logs with no changes to tune at all. It has me picking up 12-14hp and 26-27tq over my last log. But I have had better logs. IIRC, compared to my absolute best logs, I've probably picked up 6hp and roughly 20tq. Granted those were taken early march or late february and the ambient temp was probably 15 degrees colder.

What about the smoking turbo phenomenon? This and the CEL is what's scaring me off of the catless dp. But it seems like there are no cel's and will this pass our MD emissions?

It won't pass the visual test but maybe they won't look?

IIRC they fixed that smoking turbo issue for the most part with the genpu.

im running the speeddaddy egay pipe and UR cbe and its loud as fuck cold starting it. while cruising i barely notice it with the music on but others say its loud as hell. down shifting and engine braking shake the cabin though


edit: just read that you have it installed. what method did you use to connect the dp to the cbe? did you re-use the stock donut flange?

I had a raised idle from the get go when we started tuning, so yeah... But from my understanding, that was a 1st gen issue.

I didn't use the gasket. We cranked down on it to the CBE so the bump would seal it. Didn't seem to leak at all. Meh. LOL.

Corksport sells these: Mazda Exhaust Donut by CORKSPORT I don't know if that would work or not.

i actually ordered one of the corksport donuts but the dp end is too thick. i thought about just tughtening it down without a gasket. i ended up just crushing the dp into the gasket and tourqing it down as much as i could

sorry to revive this thread, but i just ordered this DP and have a few questions..

How bad is the fuel smell if it smells at all?
from 1 to ten how bad was the install? is this something that can be done in stands or it has to be on a lift?
did anybody took it to the shop? if so how much did they charge you
Also if i want to add a high flow cat is this something that i could do later on without having to uninstall the DP or i have to do it now before installing it?
Did anybody heat wrapped the DP or used any type of coating on it?

The only time you're going to smell anything is when you're at idle for extended periods of time, with your windows down. So, maybe some stop lights. If you let your car idle to warm up in the winter time, its going to smell like shit when you get in it if you leave it on for any measurable amount of time. Roll the windows down, and the smell is out in no time though.

TL;DR... The smell isn't bad enough to matter, and will reduce the amount of people willing to ride your ass.

LMAO, I was set on getting a catted CPE (Peace of mind, is a brand new car and dont want to screw it up so soon), but for 140 you just cant go wrong, my main question is that if after i install it will i be able to add a high flow cat without uninstalling it if i change my mind later?

140 (DP) +92.00 (magnaflow cat) + 35 welders fee = 265 for a catted DP, Also this aluminum runs real hot, is it recommended to heat wrap it or you just installed like that?

Thanks, I appreciate the info

No fucking clue; I'm not in the business of making custom exhausts. Take it to a shop and ask them. I wouldn't trust their opinion over the phone.

I didn't wrap or have my shit sprayed. Just make sure you get some zip ties and keep the O2 harness away from the DP.

And yes, a DP can be done on jackstands, but it will probably take longer. And as far as time/difficulty - that depends on you and your tools.

I don't really smell anything from mine. Install is super easy and very doable on jack-stands. I did mine in about 2 hours with some screwing around with other things in between.

I think i can do mine but then im scurrred that i break something or cant finish it then I`m screwed... if i do it i will start on a friday night with a couple of beers and work on it to finish it on Saturday so if something happens i still have sunday to go an call for help.

this is my DD, i will ask around on some shops for a quote on mounting it, if the price is low enough i will just have them do it, or wait till I meet the NATOR guys and see if i can get some help.

Ok, am I the only one that see's the fucked couch on the side of the road in the video?



Thanks for video, I will be getting mine in the near future and after hearing both I like the sound with the stock cbe.

Do it without the beer so theres less chance of breaking something. Save the beer for the celebration of a job well done after you've had a chance to do a test drive since its your DD.

You can add in a high flow cat down the road but its easier to do it when its out of the vehicle as the car needs to be fairly close to the turbine housing in order to keep enough heat in the system to work effectively.

I wouldn't recommend a shop unless you don't know what you're doing, and are not a part of Nator. Then again, I prefer to do my own work.

And I'm not sending anyone to Nator unless you're an active chapter member. Don't be the guy who gets shit installed and then disappears.. I'll slaughter you. ;)

Yup. Post it yo!

1:26 on the right. Abused and left smudged with shame.

Yep, Im not NATOR yet cause im fairly new, and could`nt go to the only meeting they had in that time, My Nator guys have a lot of knowledge and they have helped me with a lot of info already, Im kinda handy with tools and probably have everything i need to do it myself.

If they help me i surely wont dissapear but I work 6 to 4 and also own a cleaning business so I`m pretty much working 24/7, if NATOR helps me out then i will feel bad every time i have to tell them i cant go because of work, having said that i have my best interest of being a part of NATOR and help when and with I can. So lets see when we meet up what they think about this.

Oh, yes I've seen that, and yes I've noticed the couch. lol

Maybe he can go back and pick it up for you.

Honestly I could use some good couch penetration..... but that thing has a solid and visible layer of butt grease gathered over several decades of bare assed skin grinding human sludge deep deep deep into the shag of the material.... not that I am too good for it.... maybe we could spoon on it and watch a movie, you know, give it a test drive. I try to stay humble

I call big spoon... :hump:

Had my ebay catless on my One for nearly two years and there isn't a crack on it, getting ready to throw it on my Poo. Going dp into stock cbe for the sleeper approach but man do I miss the sounds od my rapebuilt mani, ebay catless, magnaflow cbe exhaust. Everyone that heard my exhaust said it was the most unique sounding MS3 they heard.

But I'm def sticking with magnaflow cbes. It was tame and dronefree when cruising but sounded nasty when WOT.

Any clips?

Have to see if I can find them.

They are in your old thread

I just installed a UR cbe. I can make a go pro of before and after with a testpipe. My test pipe should be going back on either tomorrow or friday.

I was finally able to get some before and after videos. The first video is just the UR CBE, the second is the CBE with a test pipe. These videos are only cruising around. The most I get on it is up to 4000rpm. I'm in the middle of a maf cal and was told to drive easy. With the stock downpipe and UR test pipe, there is definitely noticeable drone. My JBR dog bone seems to make it even louder. I'll make a video of the interior later tonight and post it. I like my shit loud and obnoxious, so I am seriously debating the UR catless DP just as a rice mod haha.


@CWP_MS3; I know its been two months, but I hope this helped if you were still undecided.

too much failure

Nope. I've been catless for 2 months. LOL. BTW, your video is "private", so none of us can see it.

Lmao double fail.. Well, its public now if anyone else wanted to see the difference.

Got my Ebay Catless Dp installed this weekend, now i got 3 CEL codes... already ordered this

O2 Bung & Plug Combo, SAVE 15%!!! - O2Bungs.com

i have to plug the current o2 bung and weld a new one that sits right on the pipe, not extended like the one it has right now, lets see if i can find somebody that can do this without taking the DP off.....

Let me know how that goes. I was considering having mine welded. I finally turned off my low voltage code and then got one later that day that said 02 sensor malfunction. I don't really give a fuck, but I hate CELs.

Im anal about cels, specially on a new car... plus the car is not running right, on WOT sometimes i feel fuel cuts..Dont want to ZZB...


I will show this picture to my guy and see if he can do it, This is atvfreek; picture, he said they did it without removing it, if i cant find anybody to do it while installed then i will probably buy a catted one from CS.....

Why the fuck are you getting fuel cut? The rear O2 only reads the efficiency of the catalytic converter. It doesn't have an effect on AFR's. AFAIK.

I dont know for sure, havent Logged anything.... Maybe im just being paranoid... i heard that the malfunction of the rear 02 sensor causes the car to run shitty sometimes sending more fuel sometimes sending less fuel... i have P2096 P0137 P0139

PO137 and PO139 are normal with this, at least from what I've thrown myself.

If you're getting fuel cut, don't do a WOT log, but see what your AFR is at idle and regular driving.

http://www.mazdaspeedforums.org/foru...t-p2098-63641/

Idle is 29.3.. running goes to 14... is that normal?

Edit: 29.3 is between shifts for like half a second idle is 14 to 14.5

I think your afrs should be around 14.7 at idle. The guys who know more about tuning can help you better, but I think your running a tad rich at idle.

probably tappin dat ass

As soon as I get rid of my cels I will start tuning with @Lex; probably by the weekend
