the reason i ask is because i installed the cattman headers in m fifth gen, took out my stillen ypipe and no one seems to show interest for it in the 5th gen classifieds, so i figured if it fits a fourth gen i might as well put up a post for it in the 4th gen clasifieds. I do have the extra short "u"shaped pipe that comes with it which i didnt need to install on my car because it says something about it being for fouth genners?any help is appreciated thanks

 

i believe it will only fit cali spec 4th gens, but im not 100 % sure

 

thanks for the reply, hopefuly i look some good stuff up on the search
