need sidepipe options to get the decibel level down

[jeffnolan]

I was at Laguna Seca yesterday and ran afoul of the sound monitors. The limit for the track is 90 decibels (I think Sonoma is 92) and while I could pedal the car by the sound station between turn 5 and 6, they still called me out on other parts of the track. I really enjoy track time but if I have to drop to 4th gear and manage my way around the track, I might as well take my driving buddy's advice and "get yourself a GT4 that you can track and also drive to work."

I'm looking for sidepipe options that will help me manage the sound output. I don't mind giving up some horsepower in the tradeoff, I have plenty of power to spare in this car so trading some off to be able to hammer it on the straights and out of the corners is a fair trade.
