Installed the badmab header and 3" zzp downpipe.
When I wot and the rpm is around 2500 and 3000 there is this rasp that sounds like an angry bee. Its not comming out of the exhaust in back, is it normal to hear a sound like that with aftermarket headers?
I read somewhere that you may hear something that sounds like an exhaust leak after installing aftermarket headers cause of the thin walls of the header, is This true?

My CA V1 sounded horrible, turns out I had a exhaust leak, now its better, but I hear a rasp too, not bad though.

^ Really?

What gasket did you use?

Maybe mine will sound better when my exhaust is installed.
