there is no exhaust on my car its a 97 civic dx coupe with a gsr motor my question is as far as a aftermarket exhaust goes what car should i order it for an Si? will that fit fine i know the dx one wont work because of where the cat was

 

get a civic EX one. 2.5" piping would be great. for the cat, i guess you dont have the gsr one. either get a hi-flow cat or a stock cat. itll keep it quiet

 

oops forgot to mention that it does have the exhaust manifold and the cat

 

I hope that your not running the engine with out the exaust manifold! Your going to burn up your valves with out pack pressure on the engine.

 

i havent drove the car yet and i just said it has the exhaust manifold

 

get a custom set up...
