Im wanting to put a catback exhaust on my 97 Civic with a 96 GSR swap, but not sure on which catback im suppose to buy. When we bolted my exhaust up to the GSR's exhaust manifold we had to drill a couple holes. So do I go with the Civic catback system or the Integra system?

 

yikes.....drill... probably the gsr. lets see what the experts think.

 

He's not running a catalytic converter because the HX has it built into the exhaust manifold. I personally said the Civic cat-back would be ideal.

 

Yep

 

cool. it's built into the manifold huh.... what a trip. i guess ya learn something everyday. mines a 94 so yeah... whatever will fit best I guess.

 

You want the exhaust designed specifically for your car. With a catback system your basically concerned with the fitment of the exhaust canister with the rear bumper (specifically when concerned with hatchbacks). If your cars an HX and your just running the B-series exhaust manifold (header) into the stock catbacks flex joint, that should still work with an HX catback. I've never tried it myself but it stands to reason. I'm not sure what you had to drill though?

 

The two bolts that bolt the exhaust directly to the header, in my case since im not runnin a cat at the moment, were to close, so we had to drill a hole on each side of them so that the bolt pattern would fit the header
