      Description

      Deep Aggressive Growl. Expect a more powerful growl coming from your Sierra with this FlowFX Dual Rear Exit Exhaust System by Flowmaster. The mild throaty sound intensifies as your truck accelerates on the road, exuding an impressive level of power and class without excessively firing up the track.

      Enhanced Ground Dynamics. The high-flow, straight-through FlowFX muffler and mandrel-bent pipes of this cat-back exhaust system facilitate continuous exhaust flow that effectively boosts your Sierra’s engine power and torque. This uninterrupted flow also maximizes gas mileage even with full performance.

      High-Strength Exhaust System. Engineered using ultra-smooth, mandrel-bent, 3-inch stainless steel tube, this FlowFX Dual Exhaust is a superb, long-lasting upgrade. The 409 stainless steel withstands the highly corrosive exhaust chemicals and the extreme temperatures caused by the intense catalytic activities. This premium tube construction and the tough, welded muffler case can durably withstand salt, rocks, tar, and other harsh elements.

      Straightforward Installation. Flowmaster designed this FlowFX Dual Exhaust System for a bolt-on installation that reuses your truck’s factory exhaust hangers and mounting locations. The installation process completes using basic hand tools and can be installed with light to moderate mechanical skills.

      Application. The Flowmaster FlowFX Dual Rear Exit Exhaust System is intended for use on 2019-2024 5.3L Sierra 1500s with Factory Dual Exhaust.

          Word on the Trail

          I'm a new & reluctant customer. So I contacted by phone & chat with several different questions about a product I needed to order. They were very knowledgeable about the product. I was given nothing less than the most professional assistance EVER, both times. I WILL be a returning customer.
