So I just recently bought an integra and it has an obx exhaust on. The car has a very very loud low rattle during certain rpms. I was feeling around by hand and I think it's because the axle back is mounted too tight up against the underside that it causes the loud rattle. Not sure if it's because of just that brand fitment or what. It also has a silencer that's stuck in it. I was thinking of just buying a Mugen twin loop to solve both rattle and silencer problem.

My question is, my goal from the start was to kswap eventually. Does kswap exhaust differ from bseries exhaust? Like if I get the Mugen twin loop and then k swap later, would I still be able to use the twin loop?

 

Just take it to a real exhaust shop and they will fabricate the K swap header to the cars existing piping.
