Also included in this exhaust system is a massive 6" diameter, polished 304 stainless steel tip with a laser-cut stainless steel aFe power badge. ATLAS exhaust systems are the perfect combination of performance, fit and value. Simple Installation: All systems use factory mounting locations providing stability and hassle-free installation. Leak-Free Seal: High quality band clamps are included for a complete 360 degree sealing surface. OE Fit: OE-style bayonet hangers are used to maintain a stable pipe location during high vibration and high heat conditions.

Flow and Performance: This ATLAS exhaust system is constructed of 5" mandrel-bent aluminized steel tubing for maximum flow. Smooth transition bends allow for low turbulence, increasing horsepower, torque and lowering EGT's. 6" Diameter Polished Intercooled Tip: Finishing off the exhaust is a 6" diameter, high luster polished, stainless steel slash cut tip with intercooling vents designed to reduce exhaust gas temperatures at the tailpipe. A unique stainless steel laser-cut aFe Power logo plate is riveted on for an aggressive style.
