This cat-back exhaust system is constructed of 3 IN - 2-1/2 IN mandrel-bent brushed finished 304 stainless steel tubing for maximum strength and durability. This system features a high-flow stainless steel high-temperature metallic black muffler, producing a powerful sound. The muffler has a high-temperature metallic black finish for ultimate corrosion resistance. Finishing off this exhaust system are quad 4 IN diameter polished stainless steel clamp-on exhaust tips. The tips features a laser etched aFe POWER logo for a unique style. This system produces a powerful sound unleashing all available horsepower and torque. Some cutting may be required, see instruction sheet for further information. Utilizing factory style hangers this system mounts directly to factory mounting locations for a 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. 100% TIG-Welded for race-proven strength and durability.
