Hey guys, I have a chance to pick up the old school jdm rsr 2.5 inch cat back. I would also be getting the jdm cat to boot. My question is will these pieces bolt up to a kamikaze header with a 2.5 inch collecter?? Because isnt the jdm catback's a little longer or shorter?? I searched but didnt find too much.....Thanks guys

 

jdm cat is 12" long compared to 17" USDM cat so you may need to cut the exhaust just before the flange where it bolts to the cat an weld in a section of straight pipe to make up the distance. If the header collector is 2.5" then it will bolt up to the jdm cat without problems.
