y pipe noise
#1
This is still happening to me, since the install last summer.
Cattman SS Y-pipe -- really no major noise when in drive or park, even under heavy acceleration.
HOWEVER, in reverse, there is DEFINITELY added noise -- almost like a leak and rattle sound both. All nuts are tight. Seems to fit fine, no gaps at all.
If it's a leak, why only in reverse?
If it's a rattle, why only in reverse?
I don't get it.![Confused](https://maxima.org/forums/images/smilies/confused.gif)
Help!

You may want to look under the car and check for clearance problems. I never had an issue with noises with my stillen pipe. But then again, some people say they don't have a problem with their cattman pipes.

Last thing which many guys do is use wrap on the flex section. This eliminates the hissing noise.
