will this fit?

I have a 2001 gsr. My friend has a 94 rs. I'm buying a comptech catback for my gsr. I wanna sell my stock cat-back system to the 94 rs owner. My question is willl it fit since they are diffrent models and diffrent model years?

the exhaust should work because most chassis related parts will be used interchangeable from 94-01

yes, it will fit
