Review on Enhance Your SUV's Performance with Flowmaster 53057 3 In(C)/Out(O) 50 Series Muffler! by Jon Robertson

For adults who want a little more growl without upsetting the neighbors and let your V-8 breathe a little easier. This silencer is for you. I recently replaced my stock muffler with this Super 50 5.3 GM (Silverado) and couldn't be happier. I paid a little more than the Super 44 that everyone buys. However, I also maintained the correct exhaust back pressure to keep my truck's 300hp heart torquey.
