Flowmaster Force II Dual Exhaust System; Side/Rear Exit (07-13 5.3L Sierra 1500)

Cat It Up. When you're looking for a custom exhaust that will provide performance improvements for your 2007-2013 5.3L Sierra 1500 but not deafen your neighbors, then you should consider the Flowmaster Force II Cat-Back Exhaust - Split Side/Rear Exit. Its superior craftmanship and solid components will keep your Sierra purring just the way you want it for years to come.

Mandrel-Bent or Go Home. When it comes to making exhaust systems, stock's modus operandi is to use normal bends in their piping, which creates pressure points and interrupts flow, choking engine performance. The mandrel-bent stainless steel you find in this exhaust keeps the 2.5-inch pipe open through every bend, maximizing flow.

Sound Profile. The attached Super 50 series muffler on this cat-back provides a noticeably different but not-too-loud sound profile. It's going to turn heads, but not rupture ear drums.

Installation. This cat-back is completely bolt-on, meaning that there's no mods or drilling required. Just some hand tools and a car lift or jack stands are needed, and maybe a friend to hold the pipes in place. This system can be configured for a dual-out-rear or dual-out-side exhaust exit. Installation should take about two hours.

Application. This Flowmaster Force II Cat-Back Exhaust - Split Side/Rear Exit is designed to fit 2007-2013 5.3L GMC Sierra 1500 models. Please ensure correct engine and model before purchase.

Tech Note. Designed for Extended Cabs with the Standard Box and Crew Cabs with the Short Box.
