Product Description

The aFe 49-46101-1 Mach Force XP™ Cat-Back Exhaust System is a high-performance upgrade engineered specifically for 2005-2019 Nissan Frontier trucks equipped with the 4.0L V6 engine. This direct-fit exhaust replaces the stock system from the catalytic converter back, using mandrel-bent 409 stainless steel tubing to minimize flow restrictions and maximize engine performance. The free-flowing muffler and polished 304 stainless steel tip work together to deliver a deeper, more aggressive exhaust note while improving horsepower, torque, and throttle response.

Installation is straightforward with OE-style bayonet hangers and heavy-duty band clamps that use factory mounting points with no cutting or welding needed. Performance enthusiasts will appreciate the refined balance of sound and power this system provides, making it an ideal upgrade for both daily driving and spirited road use. The Mach Force XP cat-back exhaust combines durable construction, enhanced performance gains, and an aggressive tone tailored to the Nissan Frontier platform. Fitment confirmed through 2019. 2020+ Frontier models with the 3.8L V6 require a different system.
