GMC Sierra 1500 Performance Exhaust - Flowmaster - Cat Back, Single Exit, Force II - Polished - ’07–’13. A refined, mild-sounding cat-back designed to enhance drivability while keeping cabin noise in check.

This Force II system routes 3.00-inch, mandrel-bent 16-gauge stainless tubing through a Super 50 Series muffler to a large single tailpipe capped with a 3.50-inch polished stainless tip. It installs after the factory catalytic converter, reuses OEM hanger locations, and is well-suited for daily use and towing. Engineered for smoother flow, it’s designed to sharpen throttle response and efficiency with minimal interior drone. All necessary parts and hardware are included, and it’s backed by Flowmaster’s Lifetime Limited Warranty. Fits 2007–2013 GMC Sierra 1500, including common 5.3L Extended Cab 6-ft and Crew Cab 5.5-ft bed applications.
