What is the difference in exhaust systems that fit a 1999 4dr GS-R but NOT a LS 4dr? I have an LS 4dr and have a hard time finding as many options as I'd like. Will both systems fit one another? I don't get it...

 

The GSR exhaust wont fit unless you cut it and weld it... the headers are shorter making the gsr longer.. But if you get a good deal on one.. Pick it up. Thats what I did.

Good luck on your search.

 

Wrong, the 98-01 Integra GSR header+exhaust is the same as any 94-01 Integra LS. Only 94-97 Integra GSR have different lenght

 

Actually, only the 00-01 Gsr's are interchangeable with 94-01 Ls

 

Learn something new, Thanks

 

So I could in theory, buy an exhaust that fits a 00-01 GSR 4dr and it will fit my 99 LS 4dr? That would give me a lot more options potentially.
