aFe Twisted Steel Exhaust Header for 2002-2013 GM Sierra (48-44001)

Product Description

Factory Mounting Locations: These headers retain your stock catalytic converters and are a direct bolt-on installation which requires no cutting or drilling to provide a hassle-free installation. Formed Collectors: 4-to-1 formed collectors decrease turbulence and increases exhaust velocity. The result is increased horsepower, torque and improved throttle response. Heavy Duty Flanges: 3/8" thick 1-piece flanges prevent warpage to ensure a leak-free seal over the life of the vehicle. Optimized Tube Lengths: Tube lengths are optimized for true pulse control technology which improves flow and performance. Emissions Disclaimer: This product is not currently CARB exempt and is not available for purchase in California or for use on any vehicle registered with the California Department of Motor Vehicles. aFe POWER headers are engineered and manufactured in our Corona, California manufacturing facility.
