I want to get a Cat-back exhaust for my 94 integra RS with a gsr swap, would i need an exhuast for an RS or GSR to fit properly?

 

The GSR is the one you need... The chassis is the same, therefore the bends are the same... but, full exhaust wise, go with the GSR....

 

What header and cat are you running on the motor?

 

GSR

 

if you are already running the gsr header, then you should complete the exhaust with a gsr catback
