anyone here have a test pipe on their car?

 

yes i have

it stinks


i had a 2.5" godspeed testpipe....used it with my 2.5" str8 pipe....

i believe that the hp difference isnt that great....as opposed to my new usage of a carsounds 2.5" cat....


but yeah, only downside for me now is, that i cant run race gas....

 

What is a test pipe? Sorry, it's a newbie question, but my understanding of the exhaust system is header, d/p, exhaust. Where's the test pipe go?

 

a test pipe goes where your cat would be
