With the release of the 6.7L Cummins in 2007.5 model year applications came an entirely new exhaust system for the Rams. This factory system features a 4" turbo back exhaust that features a catalytic converter in the downpipe, followed by a DOC (Diesel Oxidation Catalyst), then a DPF (Diesel Particulate Filter), and finally a relatively small muffler located just before the rear axle. Beginning with the 2013 models, due to increasing emissions regulations, this system was again modified to also include a DEF (Diesel Emissions Fluid) system to further control exhaust emissions. For 2019, Ram has kept basically the same exhaust system in general. The 2019 trucks feature more than 7ft of exhaust cleaning filters. No need for a factory muffler as the emissions filters keep the noise to a minimum. If you're looking to improve upon the power and efficiency of your Ram, we can help you upgrade your exhaust with a higher flowing 4" or 5" system built from aluminized or stainless steel in single or dual outlet, or even stacks!
