There is also a wide range of Flowmaster series exhaust systems, including the Flowmaster 40 series and the high-performance Flowmaster 50 Series. These mufflers and exhaust systems are crafted from high-quality materials with state-of-the-art designs and manufacturing methods including true mandrel bends for high flow without restrictions.

The state of the art Flowmaster dyno tester tracks the complete engine cycle down to millionths of a second, with exact readings of every degree of cam rotation. This continuous product development and testing ensures your Flowmaster muffler, Flowmaster dual exhaust, or cat back exhaust brings you the best possible custom-tuned performance and sound possible.

2004 Suburban was sluggish & check enine light on for cat failure. Installed these cats in less than half a day. Hardest part was getting old cats off. New ones went on smooth as silk. Vehicle runs great now & no more check engine light. Get these & make your truck great again.

This is a nice muffler. I have a 2002 Tahoe. The muffler sounds nice. I also have a 2007 Toyota Tacoma and I barely drive it now because I love the sound of my Tahoe.
