Just like all of Mel's Manufacturings Exhaust kits, it will come with all the required clamps, pre-weld contour bent hangers, and stronger flanges to help you sail through the installation process. This system will replace your restrictive OE exhaust system with a 4" high-flow exhaust system that not only sounds much better but also will improve mileage, torque, and throttle response!
