So iam thinking of getting the greddy evo 2 exhuast with a high flow cat and was wondering if its worth swapping the cat with a test pipe? would like to hear ur comments if its worth the gains and how much would i gain if i do so?
Thanks,

lol before somebody says it use search to find out about test pipes. long as you dont mind a cel just do one of the fixes i would say testpipe all the way.

 

haha thanks guys i just found a thread with plenty of discussions, thanks but feel free to throw ur thoughts in, never hurts to read more.
thanks,

 

Do it. I switched and never looked back, the car feels more torquey, more powerful, and spools faster. If it's too loud, consider the buschur bullet testpipe. I love mine!

 

did u notice any lose of power going from a straight test pipe to one of those resinated test pipes?

 

no u won't notice a difference. You can hardly tell a difference from a test pipe to hfc.

 

test pipe all the way

 

i have been hearing both sides of the story where with a test pipe, the torque gains are great. i guess i won;t find out till i try both. but hey i have a question on some of the states with emision testing. lets say i was towing my car back from the track with a test pipe on, and i needed to go get it tested for emission for plate renowal, could i just swap the test pipe with an hfc and do the test? and put back the test pipe whenever iam offroad?
Thanks,

 

test pipe. you won't regret it

 

if your worried about passing inspection just find someone to let you borrow a stock cat, swap it in then swap it out after inspection

 

ya that was my questions. thanks . i just didn;t know it was that simple.
