Review on Enhance Performance with Flowmaster 8425454 Super 44 409s Muffler - 2.5 In(D)/2.5 Out(D) by Jonathan Clark

Revainrating 5 out of 5

If you want louder.

Put this on a Chevy 2000 2500 6.0 twin muffler. The duals were behind the rear wheels. It's a little louder than expected. Drones are around 1800 RPM, which translates to a cruising speed of 55-60 mph. I'm afraid it will be too much if I pull a pontoon boat. I have to wait and see.
