Evan, Steve's heard it, he can chime in.
If it isn't an exhaust leak, it's so bad I'd have to say that my plenum is cracked.

The volume/pitch changes on whim.
Greg says that he heard it, and it was light, but went away when it warmed up.
I wound it up to 4k, heard a hiss then it let open and gets loud, alot of the time.
Greg's guessing it's a bolt/gasket on the exhaust mani.

I'll take off my plenum *before* the pull just in case and inspect the plenums, but I'm not holding out hope.... :-\


Maybe someone that owes me lunch will go over to Steve's and lend me a hand? ;-D
