I have a guy that might want to trade his 2 1/2" off-road pro chamber for my Mac h-pipe with welded on high flow cats, will they be interchangeable between our cars?
Should be the same the only differnce will be the exhaust hangers point in the wrong direction. Fox hearders work just fine on our cars (minus egr bung) and we can use 96+ cat backs just fine a well (minus the hangers facing the wrong way).
I know the catback on ours is slightly longer. I'm pretty sure the H-pipe is the same except the hangar (which I don't use anyway due to the TKO500...).
