what is the hissing sound after every rev?
it sounds like metal rattling or an escape of air. Is it the test pipes that cause that noise or the CBE?

That's the VQ 1800rpm hiss.

Dunno if older 35DE's and Revups do it, but the 37's and HR's all do it.

I've got longtubes and mine does the same thing with a stock cat back.
