Question about a crack test pipe~help!
im planning to run my S on the track, but my test pipe crack half on me, so would i be losing any hp or should i just put the stock cat back on or is fine..but right now it sounds like shit but when when it hit vtec is like a monster..any suggestions that i would be losing any power?
um... what testpipe do you have? that is the first time i ever heard of atest pipe cracking. I say you should put your CAT back on. if your TP were to fall off on the track you could damage your car and others.
