Hi-
I am heading for an SCCA track day at Laguna Seca with my RSR. My class is limited to 101 decibels. My car has the stock Supertrapp header with 4 disks. Does anyone know what 101 decibels even sounds like? Just in case I bought a regular muffler and pipe, which I can quickly install, but would like to run with my current exhaust if possible. Any thoughts? Thanks, Bill Pierce

Watch where you run up the hill from T5 to T6 as sound readings are taking from both sides of the track (you'll see the sound shack on driver's right just past the exit berms at T5.)
