I know almost nothing about exhaust technology, let me get that out of the way.

But it looks like you have a 3.5" tip on that system. Did you look into finding a silencer that fits in the tip, the kind that's secured with set screws?

Mine's way too quiet at the track, I can't hear it through my helmet, but I wouldn't want to drive around town with a track exhaust either.

So, at the risk of sounding like an idiot....I've been playing with the idea of making an adjustable exhaust like they have for motorcycles (I think it's called the Jeckyl and Hyde exhaust). I've seen different kinds, some even work like a valve and have an electric servo wired to a knob so it's adjustable on the fly. I assume that in addition to decibles, it would be a backpressure/velocity adjustment also, and therefore you could fine tune your torque up or down the rpm range?
