i installed the kinetix test pipes with the borla exhaust a few weeks ago and as i am coming to a stop and the RPM's are coming down i can hear a hissing noise. sounds like the flow of the gases through the exhaust. is this normal, any suggestions?

the h-pipe had this probelem when i had it installed but then they welded it and it went away. I am thinking it has to be where the test pipe and the exhaust joins together. I was thinking i might be able to exchange the gasket that is used between that area with a different one.

It sounds like a leak and then like if the exhaust is rubbing. Im taking the test pipes out cause its driving me nuttts. goin for resonated just to check them out. :werd:
