You'll always have drone with the baffles open at low RPM regardless of what else you do with the rest of the exhaust, open exhaust at low RPM under load = drone.
Makes perfect sense, thx.

It might be a little cramped to do this properly but even an attempt is going to get rid of a lot. Its a lot of work when you can just close the exhaust valve

That is quite an answer by ra! But one would have to plug in whatever is the resonance range for the C6, do the math and then figure out how it will all go together. That's a lot of work but may be worth it if the space is there.
