Description
Cat-Backing With Class. When your 2007-2008 GMC Sierra 1500 needs a custom cat-back system that provides a maximum performance increase but also doesn’t blow out your windows, you need to get yourself the Flowmaster Force II Cat-Back Exhaust – Split Side/Rear Exit. The quality construction means that you’re getting optimal flow and performance increases while making sure your Sierra sounds great.
Mandrel-Bent. The 2.5-inch stainless steel tubing is completely mandrel-bent to ensure maximum flow over your normal stock exhaust. From there, the stainless steel piping provides durability and resistance to corrosion.
Sounds Like Awesome. The cat-back system includes a Super-50 Series muffler that gives your exhaust note a noticeably different and more aggressive tone, however it’s not too powerful, meaning the interior notes are relatively quiet and the exterior is powerful but not overpowering.
Installation. This is a completely bolt-on install, only requiring hand tools and a car lift or jack stands. You might need a friend to help you hold the pipes in as you secure them in. It should only take about two hours. Finally, this cat-back can be configured for a dual-out-rear or dual-out-side (DOR/DOS) exhaust exit.
Warranty. This cat-back system is protected by a lifetime warranty against material and manufacturer’s defects. Please see Flowmaster’s complete warranty for additional details.
Application. This Flowmaster Force II Cat-Back Exhaust – Split Side/Split Rear Exit is designed to fit 2007-2008 4.8L GMC Sierra 1500 models. Please ensure correct model before purchase.
Tech Note. Fits All Wheelbases except for Extended Cabs with the Long Box.
