A back to back sound clip compilation comparing the difference between dual Flowmaster 44 series mufflers with turn downs at the rear axle and dual Spintech 9000 Pro Street mufflers with turn downs in the same location. All comparisons are using the same header and x pipe combination with BBK long tubes and a BBK x pipe. Engine set-up is a 306 SBF, E303 cam, Trick-Flow Twisted Wedge heads with an Edelbrock upper and lower manifold, Vortech supercharger on 9lbs. For those looking to make a change in sound I hope this video was helpful, but the clips of the Spintech mufflers do it no justice-they are extremely aggressive, loud, and create a deep drone at low RPM under load. I’m sure tailpipes would help, but if loud is what you want, that is what you’ll get.
