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?

i have heard this on other z's and g's but i dont know whats causing it

Sounds like a leak..Check the Borla for leaks especially where it joins together like an H pipe...Some guys actually had to wrap that with exhaust wrap to stop it..The Borla needs to be installed perfectly not to leak...

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.

:banghead: yup ... same noise... got my test pipes done and i also have borla td and have the same problem. I read in a g35 forum that this was normal. 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:
