Semi Truck Performance Axle-Back Exhaust Systems

If you're looking for a louder exhaust this isn't it. It is no louder than the SS1 exhaust. But it is deeper. It is a quality muffler but the claims they supply will not work. So plan on buying different clamps or welding.

Love the deep sound from the exhaust now! Tons better than stock, better gas mileage, and better acceleration too. Had it professionally installed, and it was done in about 20 minutes! Definitely recommend Flowmaster Products for ease of installation and high quality!
