CP-E Down Pipe - Do I need a HPFP

[mutiger93gt]

I have a 2009 Mazdaspeed3. It currently has about 30k miles and I have the following mods:

Corksprot Boost Tubes
Hypertech Reflash
CP-E Cold Air Intake
COBB Turbo Inlet Pipe
CP-E Top Mount Intercooler

I am trying to figure out if adding the CP-E Downpipe with a cat, would require me to add a HPFP? I know that CP-E offers the full HPFP but that there are two manufacturers that sell the components to swap it over to the higher pressure version.

I know I have read several threads and I don't really have a good concesus either way.

Yes you need a HPFP. You can do either the full HPFP or the internals. There was a nice group buy going on for Autotech Internals....Need to be VIP member to access though so donate and hit it up:

at least this isnt in the genpu section.
Yes you do need to upgrade.

So usually I would tear you a new one for that question but your only 4 posts deep so you have a bit of an excuse....

Get the fuel pump internals, dump that piece of shit hypertech and get an AP. If after those 2 things you wont have money left over for the downpipe- dont get it yet.

Also, theres nothing wrong with the cp-e downpipe but I personally don't like the way that company operates and won't ever buy anything from them.

Look into these instead:

Corksport(What I'm gonna be runnin- well the ms6 version)

Mazdaspeed 3 Downpipe CorkSport

COBB Downpipe:

yes you need a pump > i have the CPE pump. works great !

I'd say ditch the hypertech, and spend the ridiculous CP-E dp cost on a accessport. You'll get equivalent gains from the accessport that you would the downpipe, and at least at this point you won't need a Hpfp, and you'll be losing the lame HT.

Forget the CP-e DP.

Buy AP, and internals

Then

Buy the CNT catted downpipe for half the price of the CP-e...

I, and many others did, and it's just as good.

Or, like me, the ebay dp, which is doing great for me even with BT. and it was $150.

+1 on CNT catted DP. smells like there's not even a cat in there, sounds great with the CNT CBE too. There's just one bolt that is almost impossible to get a wrench to.

I don't normally preach for people to donate but everything you need is currently in the FS section. Catted dp's and AP's. Plus there is a group buy on the best internals out there like someone already mentioned.

I've actually read several post's regarding how shitty the CNT catted dp is. Seems like its actually more restrictive than factory dp according to a few tuners here. Quality is nice, but the cat is no good.

Links to posts?

I have been running it for 10K. Def not worse than stock. Don't know who said they are, but claims like that should be backed with proof.

I'll try to find the exact posts, but it somewhere in the Battle my virtual dyno thread.

I was able to buy the CP-E used for $285 shipped. I might just sell it and sell the Hypertech and get the Cobb AP. Do you think I should just keep the CP-E since it was so cheap!

Which of these two kits you do you all think I am better off getting? I see there is about an $80 difference in each.

KMD Tuning High Pressure Fuel Pump Kit for 2.0T FSI

Autotech Hi-Volume Fuel Pump UpGrade Kit 2.0T FSI

Autotech hands down, but they are much cheaper through the vendors on this site. Plus there is a group buy still going if I'm not mistaken. Here is a link where they are 350 shipped. Let me see if I can find the group buy link. Can you tell I'm bored today?

Wow. Good info. Thanks

This makes me want to look into my cnt catted dp

[MSMS3]

OP: If you haven't spent your money yet, consider the AutoTech CDFP internals and keep your HT tune for the time being. HT tune works very well with bolt-ons, including a catted or catless dp (see mods below), and even fully bolted, as long as you stick with the stock K04 turbo.

You can always go AP later, if you really want to. Get the internals, then add the downpipe.
