It sits close but doesn't hit anything. I can't imagine a downpipe that was 3 inches that wouldn't hog up the limited amount of space down there. It clears the stock tie bars also. No leaks no rattles for me and great gains.

 

I'll keep an eye out for you, but ultimate racing makes 2.5 high flow cats. You should check them out, I hear nothing but good things from them.

 

Happy with my DP and the gains it gave..... A good way to make some easy power.....

 

Any dyno numbers.????? People say it is a great mod, but every dyno that I've seen that has tested the downpipe exclusively has negligible gains... There was an article posted by a tuner magazine that broke the gains down... I'll try to find it... I was less than impressed...

I would bet that a test pipe and catback make more power than a downpipe, highflow cat and catback...

 

Not Sure about #'s. My full 3'' Turbo back made huge gains..........

 

Thanks. My catback is actually Ultimate Racing too!

 

This is the only article that I've seen to test the downpipe on a dyno...

RMR DP dyno'd at Turbo Trix had a 21 WHP gain..... well worth it IMO.... I found the turbo spooled up quicker when I put it on.....

 

FANTASTIC article; shows 20hp and 20ftlb tq for entire exhaust with mild gains from the downpipe - what I can't believe is THEY DIDN'T REPLACE THE CAT???? Therfore they got a fixed restriction - wonder what a hiflow cat would do for the numbers

 

great link

 

email ttz the rmr DP gives more hp than that hole set up... and they have dyno sheets to prove it

 

Post the link with this Rmr DP.

 

as i said email turbotrix they have it on there dyno sheet..... I saw it personally when i was down there... 21 whp just from the DP.... stock cat and stock catback......talk to mark or jeff

 

Grod is right ... We did have like 20whp gains from a dp.. Every evo is different.. but that was done back to back ..with an RMR dp. I do know that the stock cat is the biggest power robber in that car. A stock exhaust with a cat delete would be better off then a dp and cat back ..any day. Just an fyi... The car detonate soo easy with a stock cat and mods..

for xtang --> theres little point of installing JUST the 3 inch DP if the other bottleneck isnt freed up... thats why you see negligible gains during an exclusivly DP testing
