I think, being the kind of people we are, our perception of what is or isn't "too loud" is a little warped. Flooring the car through 2nd or 3rd is a great way to find out if there are any cops within a half mile radius  It sounds great to me though, and it's pretty damn quiet at warm idle. |
I think the VVEL system allows for very tiny openings @ idle, because after the first 15-20 seconds, the car isn't loud even open header.
I've had Mandingo's old Y pipe on the car with no other exhaust (just enough pipe to keep backfires away from the O2 sensors) and have started/ran the car periodically to keep everything moving inside the engine and it barely sounds like anything beyond a modded car at idle after that first bit.
Of course, the racket it makes when you wrap it up to 4-5K without an exhaust is... well... The neighbors can't be the biggest fan of me at this point.
