Product details

This cat-back exhaust system is constructed of 2-1/2 IN - 2 IN mandrel-bent brushed finished 304 stainless steel tubing for maximum strength and durability. Finishing off this exhaust system are dual 4 IN diameter stainless steel exhaust tips. The tips features a laser etched aFe POWER logo for a unique style. This system produces an aggressive sound unleashing all available horsepower and torque. Utilizing factory style flanges and hangers this system is a direct bolt-on system, which requires no cutting or modifications for a hassle-free installation. This system features a crossover balance tube designed to equalize and distribute exhaust pulses reducing drone, and improving sound. This system incorporates factory style pneumatic exhaust valves. The valves open the 2-1/2” Muffler bypass tube or direct the flow through the 2 IN loop pipe that replaces the factory side mufflers. A mitered merge collector is used to decrease turbulence and increase exhaust velocity resulting in increased horsepower, torque and improved throttle response. State-of-the-art computer-aided design technology is utilized for precise vehicle fitment. 100% TIG-Welded for race-proven strength and durability.
