don't like the closed sound much

When I'm driving the flappers make it a lot more pleasant to hold a conversation or listen to the radio. But get on it, and look out!!!

Ultraflow mufflers now have a spring loaded flapper muffler that is supposed to significantly cut noise and then open up at WOT, but they aren't vacuum actuated.

There is a great discussion going on at the Registry about the Z06 exhaust tips and mufflers.

That sounds great nice tone to it.
You have cams in that?
