Buzz in exhaust
 

So since I've installed the long tube headers and Mac Pro H pipe I've had this annoying buzz at 2500 rpms to 3500 rpms I thought maybe it was just the Flowmaster mufflers but I have since changed to GT takeoffs, it's much quieter, but still have the annoying buzz any recommendations for fixing that damn buzz

I think I read where you have to stagger the 2 mufflers so one might connect a little bit closer or farther away. I think it changes the frequency just enough.

Or I might be nuts.

Are you refering to rasp as the "buzzing" sound?
