Fits

The 421024/422020is a 4" turbo-back exhaust system for the 2003.5-2007 Ford F-Series. It replaces your restrictive OE exhaust system with a 4" mandrel-bent exhaust system and includes a high-flow muffler for street applications. 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. It not only sounds great but also improves torque, mileage, and throttle response.
