what exactly is a test pipe?
from what i've been reading i think it goes where that cat is supposed to be but i really have no idea. someone please inform me.

also can you have a cat and test pipe on at the same time?

thanks guys.

 

let me help u out with that one search lol nah its like a resonator it does take the place of the cat u could use both but that would be a waste with yo hks exhaust might be cool for a stock exhaust system though

 

thanks for claryfying that for me man. thats what i was thinking.

hahaha did you just finish reading that thread with that dookie guy?
