2021-2022 BMW M3/M4 MACHForce XP Cat-back Exhaust by aFe Power

This cat-back exhaust system is constructed of 3" - 2-1/2" mandrel-bent 304 stainless steel tubing for maximum strength and durability. In addition, this system features a high-flow stainless steel muffler, producing a mild sound. This exhaust system finishes with quad 4" diameter carbon fiber 304 stainless steel clamp-on exhaust tips featuring an aFe Power logo for unique styling. This system produces an aggressive sound unleashing all available horsepower and torque. Some cutting may be required; see the instruction sheet for further information. By utilizing factory-style hangers, this system mounts directly to factory mounting locations for hassle-free installation. A mitered merge X-pipe is used to balance and evenly distribute exhaust pulses traveling through the exhaust system, minimizing exhaust drone and maximizing scavenging. This system incorporates factory-style exhaust valves, which use the factory exhaust valve motors (not included). The valves help regulate, direct and control the flow of exhaust gases by opening, closing, or partially obstructing passageways depending on throttle position for maximum performance. State-of-the-art computer-aided design technology is utilized for precise vehicle fitment.
