I'm getting a loud whistle from my test pipes/exhaust. Can't figure out what it is. The pipes are connected tightly, clamps seem to be fine, but there is still a whistle.

I'm using the stock gaskets, should I have gotten any from borla? or with my test pipes? what can I do to find out where this whistle is coming from? form the sounds of it, seems to be from right under shifter, towards passanger side more.

 

Also, these headers are ceremic (however you spell it).. not sure if that makes a difference vesus stainless steel headers??

Help! I hate this sound!!

 

Use some header wrap around the H pipe before you clamp it. The top of the H pipe leaks.

 

Yup, my H-pipe on my dual borla leaks too. I was going to have Midas throw on a nice weld bead, but I think the header-wrap is a good idea. I will try that. The exhaust leak sounds like a spudder, not a whistle, but it is driving me nuts.

 

So you guys think it's my H pipe which is leaking and not the test pipes?
