^^ Interesting.

So I get that the VQ naturally makes this hiss, but I don't understand why it can't be tuned away through exhaust design. I mean, at the end of the day we are just talking about gas going through some pipes and chambers.

But the fact that it comes from the y-pipe is very good to know. I wonder if this means the y-pipe could be engineered somehow, in the same way the ART pipes were engineered, to reduce this type of noise. Luckily, Tony is on it!

Does anyone have experience with test pipes used in conjunction with different aftermarket exhausts? I wonder if some cat backs are better at eliminating the hiss than others.
