I'm thinking of getting the PDE dp... has anyone have it on their ride??? If so what kind of hp gain can I hope to get??? ... Thx

i dont know specific hp gains, but i had it on my car for about 6 months and it was great. no check engine lights, the sound of the turbo, and sheer top end performance. i loved it. the only thing i did not like is that it did not have a bell mouth design where it meets up with the turbo. i recall there being a downpipe exactly like the pde, but it has a bell mouth and its cheaper. i will look for it again.

I thought that uppipes in general don't give any HP gains but it just frees up HP because the stock one is very constrictive...

i think he is referring to the downpipe. none the less they both free up hp and are very noticable.

uummm, isn't " free'n " up, and " creating " horsepower the same thing?? just a nOOb thought....

well, same result anyway.....just post whoring :).....gotta get a jump with the new system'n all :p

an upipe is a good starter mod - as for brands the greater of the selection slips my mind; when I get home, I will look up some recomendations for yah.

//asc :p

in my opinion freeing up hp would be like an up pipe, any exhaust component, under drive pulleys.

creating hp would be adding a larger turbo, turning the boost up, nitrous oxide.

Check out the Helix downpipe from Gruppe-S. It's similar in design to the PDE pipe, but it costs a helluva lot less and includes a true bell mouth piece that it CAST and not the standard issue stainless cut and welded.

I read the book maximum boost and in there it is recomended that the best downpipe is one that separates the turbine and wastegate exhaust all the way to the bumper. My choice is the bosal DP it separates the exhausts but it doesn't go all the way to the bumper so just like any other mod you do it is a comprmise.
And you can't beat the price $270US

have you looked into the dp at www.exhaustdepot.net ?

I've heard that it leaks.

ooops, my bad. You're right, I didn't even see that...

The PDE is cool cause you get no cel but save some cash and get and HKS and take it to your local exhaust shop and have them weld that little elbow on it so that you o2 sensor reads what gets traped in there. By theory this should take care of the cell. I be trying this and will post how it works.

Dude, I love my P.D.E down-pipe! Best money I've spent on my car!

blah blah blah, .... PDE sucks!

BPM ROCKS!! ;)

bpm is really nice also. if i could get any particular unit i would ge the vishnu or the turbo xs.

I've heard that they leak if not installed right.

I would think any exhaust would leak if not installed right. ;)

I did the PDE downpipe and fit/performance are top notch and no CEL. Only mistake I made was not biting the bullet and doing the up pipe at the same time. Whichever dp you choose, you will be absolutely amazed at the change to the spool up and zing it brings. As the ad says.....just do it...you will love it!

I'm waiting for Buschar's dp.
