I'm trying to prep my car for laguna seca. Their sound limits are 92 decibels and the readings are taken at 50 feet from the track apparently.
I'm currently running 2 chamber flowmasters with an h-pipe, 2.5" diameter. Dumps behind the rear axle...
its... loud to say the least

first an x-pipe setup will quiet it down and give you more power or at least a better curve that the h-pipe.
and second i would bet money that you will gain power by going with a straight through design like the borlas or magnaflows over a chambered design and be quieter
i prefer the sound of borlas but magnaflows are a little quieter...
