I have a 01 GSR engine in my 00 civic EX. At the shop i got the swap they had to make a pipe to go from where the header ended and the stock EX cat was. When i get a catback what car do i need to get it for so that it will hook up to the GSR header?

 

if the EX cat on your car is in the same location as before since they had to fabricate an extended pipe from the header to the cat, you should be able to fit any exhaust for the 01 EX Civic.

 

I would rather just have it from the header though. They just kinda welded the pipe in there. He said when i get exhuast i should just get somethign that will hook up to the header.
