Mel’s Manufacturing Exhausts are designed to fit all wheelbase & cab configurations unless otherwise specified.
Looking to wake up your L5P? The Mel’s Manufacturing 431024 is a bolt-on 4″ downpipe-back exhaust system for your Cab & Chassis L5P that will replace the restrictive OEM exhaust system. 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. Not only will this make your 6.6L sound great, but it will also increase airflow, MPG, and torque while lowering EGT’s!
