interesting design. i don't think you need the sound resonance chamber though. a lot of the downpipes such as berk, ar design, icarbon, etc don't drone at all.

There are so many factors that affect the way an exhaust sounds. I'm sure the resonance chamber serves a purpose on this design. Regardless, this thing makes 14hp and doesn't drone, so it's hard to complain right?
