First, what would a header leak sound like? I'm getting sort of a buzzing sound from the front under acceleration, but I'm not sure if this is normal. I had them use the Stage 8's, maybe I am just being paranoid.

Second, should I open the Borla up all the way or no?

 

header leak's usually sound like a tapping rocker but not as metallicky..<sp> go over your bolt's again just to be sure.. how did you seal the slip fit? quite possibly could be a heat sheild as well.. As far as the borla.. LET ER RIP!!!!!

 

I had a lot of buzzing from a bolt and socket I didn't know I dropped in the pass. side collector.

 

I never thought about that one...
