Choosing a Downpipe

[reddeerspeed3]

I put in the CS DP with stock TP/CBE, little more growl and way less turbo lag. still sounds stockish though. put on the rest of the TBE and now anyone who doesnt know what a ms3 is asks if i swapped a STI motor in. its very deep rumble at idle, almost v6ish maybe? at WOT its definatly sex.... 10x better in person than video

cs is the way to go. Best sound you can get by far. Also, I wanted to have it sorta quiet for normal driving then loud when I wanted it soooo I had a guy use one of my to cs test pipes to fab up a QTP e-cut out and... amazing. Back to stock for me though since the explosion. everything is for sale just been to lazy to make a thread. PM me if anyones interested.

Hmm well shit lol and here i was thinkin the txs catback and everything was the loudest deal for our cars. Oh well lol

i was just wondering with just adding a corksport dp, or any for that matter, how much louder will it be over stock exhaust?

Not much louder, actually less of a droning in the cabin. It just gives it a more throaty sound.
CS DP/RP with stock catback IMO is the perfect sound.

corksport dp is great. easy install had no cels and adds great tone to the car with a tp. i did boost cut like a bitch thought when i got it. now cornerfreak is making great use of it.

Ha, I didn't know that was your old DP. That thing went in so smooth. It was such an easy install. It practically jumped on the studs by itself. Everything lined up in one shot.

How long did you run that before selling it to Brian?

sorry for the dumb Q? but what do u mean u boost cut? im kinda new to FI cars and engines

[reddeerspeed3]

your turbo hits 19psi because reduced backpressure = faster spool, and the ecu/ebcs cant compensate so it closes the throttle body to prevent a lean condition. its like hitting a brick wall, then boosting again, hitting wall, boosting, etc.

[the518speedster3]

now what is a solution to this?? is there something that will help this boost cut out?

[darth vader]

You can drive around the cut by getting into the gas a little slower. Whacking the throttle open almost guarantees it on a cooler day with DP + RP and intake mods.

Alternatively, you can put in a manual boost controller and set the boost wherever you want. There's enough wastegate on this turbo to avoid boost creep easily.

[erod550]

Would a Standback or Cobb AP also be able to control the boost to avoid overboosting and getting boost cut?

[reddeerspeed3]

yes, and its far better than a MBC. AP lets you control it in a similar to stock fashion with load tables, SB just acts as a MAP clamp and EBC

[DCLXVI]

does the ATP CEL trick kit work as far as no cats go for the corkport?

[reddeerspeed3]

the CS DP comes with a 02 sensor extender that does a very good job of keeping the CEL away. i'd say on average i get a "O2 sensor slow response" code once a month. clear it with the DH and carry on.
