alright, first off, i know that this should go in the sticky about exhaust, but it is in the sticky and no one has responded so here is my question. my friend just bought flowmaster 40s for his 96 stang, and he realized he needed o/o instead of o/c my car is set up with c/o if i bought them from him, can i put those mufflers on it? if they were on backwards, would it sound horrible?

 

Get rid of the short terms like o/o, I've never heard of that.

 

Offset/Offset. Inlet and outlet... But anyways, I've never heard of anyone running flows backwards but I doubt it would sound good since they are made to flow one direction.
