      Description

      Enhance Your Rig’s Sound. It’s easy to overlook how much of a difference your exhaust system makes. It’s up to your exhaust to funnel air out of your engine. This process affects everything from your rig’s horsepower to its fuel mileage. It also determines the kind of low rumble your rig produces. With this Flowmaster Force II Cat-Back Exhaust, you gain an enhanced, deep, aggressive tone that is fitting of your tough machine.

      Gain Improved Performance. On top of the tremendous sound enhancement this exhaust system makes, it also contributes to multiple performance gains. Due to this system’s chambered muffler design, 3” wide diameter and mandrel-bent tubing, you gain increased exhaust flow too. This improves horsepower, fuel economy, and even passing power.

      Rely on Strong Construction. The tubing of this system is made out of 409 stainless steel. With a natural finish, this durably-made system is also protected against corrosion. It boasts a 3.5” inch diameter tip that is made out of sturdy 309 stainless steel and polished. The tip looks as high-end as it is high-quality because of its unique round, slant-cut style.

      Installation is Easy. As a direct bolt-on upgrade, you can expect the installation of this exhaust system to be easy.

      Warranty. A limited lifetime warranty is included with this exhaust system upgrade. See the manufacturer information for details on the warranty.

      Application. Your 2007 to 2008 4.8L GMC Sierra 1500 will roar aggressively, and perform powerfully with this Flowmaster Force II Cat-Back Exhaust installed. It fits all wheelbases except for extended cabs with long boxes.
