By: Flowmaster | 06/20/2018 < Back to Motor Life Home

Flowmaster offers a wide variety of exhaust systems for most popular vehicle applications that produce that deep, legendary Flowmaster sound in mild, moderate, aggressive, and very aggressive tones. Flowmaster exhaust systems are widely available in Cat-back and Axle-back configurations and aluminized or stainless steel construction. In this video, Steve installs and compares three of our most popular series of Cat-back exhaust systems: Outlaw, American Thunder, and Force II and then tests them out on a 2015 GMC Sierra 1500 equipped with a 5.3L V8 so that you can see and hear the differences in design and sound.
