What kind of added horsepower should I get with an up-pipe and down-pipe? Obviously using different up-pipes and down-pipes will give you different hp readings, but what is the average gain. What combos do you guys have on your cars, and what hp did you get with that combo? Also, what was the costs for the combo? Sorry for all the questions, but I am really looking at getting an up-pipe and down-pipe and just want to make the right decision. Thanks!

 

i would also be interested to hear the pros and cons of different up pipes and down pipes...

 

I've got the Helix up and down. I got mine from Gruppe-S for $450 shipped including all the gaskets and bolts and CEL fixes. I've heard claims of about 30 hp at the wheels with the combo. That sounds about right to me. The parts are VERY nice and the quality is exceptional. I have to also HIGHLY recommend a Cobb AccessPORT with the new exhaust. A catless setup with the Cobb Stage 2 programming should get about 230 awhp. That's what I've got now and I absolutely love it!

 

i have helix up and down pipes

i got em from gruppe-s for 400 shipped

great quality and a good gain

i put down 222 to the wheels with this at ATP dyno

 

get perrin up and dp since everybody else has helix. Be different! Perrin is also good too.

 

I got my helix up pipe from gruppe-s and my helix down pipe from suby dude. From what ive heard others say at different meets and such is that they are good for about 20 to 25 whp.

 

i also got the helix uppipe/downpipe combo, but from mpj performance. got my car dyno'd today w/ only those 2 mods. i took off my catback cause i ordered a stromung catback.

got about 200hp/200tq @ atp's dyno.

 

I have a HKS up- and down pipe, I've been running totally catless for about 3 months now and no problems with a cel, I paid about $255 cuz i work at a audio store we do performance so its nice to get cost on my parts

 

i think the biggest gains (besides a bigger turbo) would be felt from doing just the up-pipe and downpipe, full exhaust and a good tune, i guarantee it.
