Before testing this exhaust, I didn’t realize how much the stock setup muted my truck’s performance and sound. Once I installed the Flowmaster 718100 FlowFX Cat-Back Exhaust Kit, everything changed. The deep, aggressive tone is instantly noticeable, and I gained measurable power—up to 11 hp and 15 lb-ft at the wheels. It’s built with dual 3.00-inch mandrel-bent stainless steel tubing, which really boosts exhaust flow and durability, especially during tough drives or towing.
This kit stands out because it combines performance gains with a sleek, custom look—thanks to the black ceramic-coated tips. Plus, installation is straightforward with factory-style hangers and hardware included. Compared to other options, the Flowmaster’s “straight through” muffler design not only amplifies that deep sound but also improves flow without drone. After thorough testing, I can confidently recommend this product for anyone serious about upgrading their 6.2L F-150’s exhaust for better sound, power, and longevity.
