Some pics of my rear mounted turbo build for my RX8

You don't say. I wouldn't have thought that the turbo would make that much difference. The length of the exhaust before the turbo must muffle quite a bit. Any turbocharged car I've heard in person with either an open downpipe or an exhaust cutout was very loud at idle and cruise, and you couldn't hear a difference when the wastegate opened. Even a TT rear mount C6 Vette was much louder than stock.
