Finishing off this exhaust system are dual 4 IN diameter carbon fiber 304 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.
