Hey guys, i want to do some exhaust work and was wondering wheter i would get woth it gains if i did just a high flow catalyic converter and a warpspeed y-pipe? I want the whole warpspeed but i dont have that kind of money extra. And feel free to recommend a good catylic. Thanks

 

y-pipe is the way to go its the best bang for your buck you can get, as far as the cat back system i haven't heard anyone say anything about noticeble performance gains just more sound.

search through the forum and you'll find a ton if info on this

 

Y pipe and cat replacement is where the performance improvement is. Catback is where the sound quality (or lack of) is.

 

if u get the y-pipe from warpspeed, it is $200 ($160 with discount) and the cat is i think $100 all isnt incuding shipping, the whole warpspeed system is $590 i think there also might be a discount also.

 

i got my y-pipe for $160 SHIPPED.

 

If you don't have a clogged cat, there really is no reason to replace yours.

Unless you are burning lots of oil or running really rich, usually cats last a long, long time.

The y-pipe is the best "butt dyno" mod I put on my car. The Fidanza flywheel is second.

 

what would be more effective if u already have a y-pipe, cat OR muffler?

 

if the cat is still in working condition will a shop even pull it to put on a new one? i thought i read awhile ago that its illegal for a shop to remove a working cat.

 

Bingo!
$2500 fine
