Current mufflers are Stainless Specialties ,straight through large ID about 2.75 but am not sure.

Engine: Shelby Aluminum Block, 14.7 to 1, raised port Blue thunder heads w/offset TD rockers. 498 CID, roller cam 287/292@.050 .780 lift, 2 1/8 primaries 3 1/2" collector, peak power 7600, peak torque 5500. I think the cam and compression are responsible for a majority of the noise. Flowmaster said I would lose power but could not give me a %. I thought someone might have tried them since they were developed for this market.
