Today i noticed a noise i never heard before and was wondering if it could be a Leak in the Exhaust or no. I kneeled over by the rear wheels of the G and could hear this tsss tsss sss coming from what i beleive to be my exhaust. The car was in Neutral. I have an Aftermarket exhaust and Y pipe with OEM Cats since i havent installed my Berk HFC yet. I was wondering has anybody ever heard this noise and if so is it a leak? This is the first time i hear it i have never heard it before.

 

I was wondering the same thing I also here this

 

^ Yeah and whats worse is that once you know that noise is there it wont go away till you find out why it does it. I havent felt any different of less power im just curious to know
