Product Description

The MBRP DAL401 down-pipe kit is engineered specifically for Dodge Ram 2500/3500 trucks equipped with the 5.9 L Cummins diesel engine built between 1994 and 2002. By upgrading to a full 4.00" aluminized steel down-pipe, you'll benefit from significantly improved exhaust flow, which can lead to lower exhaust gas temperatures (EGTs), enhanced turbocharger response and overall improved engine efficiency during heavy towing or high-output diesel applications.

This direct-fit kit uses the factory turbo mounting points and is designed for a bolt-on installation. The aluminized Installer Series construction provides a solid balance of performance and durability - ideal for truck owners who demand performance without the premium cost of stainless steel. Because fitment is confirmed only through 2002 for this engine platform, if you have a later model truck you'll need to verify compatibility.
