GM Duramax L5P Down-pipe Back Race Exhaust System (2017-2025)

This DPF Delete Downpipe-Back Race Exhaust is designed for 2017–2025 Chevrolet and GMC 2500HD and 3500HD trucks equipped with the 6.6L Duramax L5P engine.

This system starts at the downpipe and replaces the factory exhaust from that point back. It removes the catalytic converter and DPF filter, reducing exhaust restriction and improving exhaust flow. The high-flow design helps exhaust gases exit the turbo more efficiently, supporting increased power and better engine response.

Built specifically for the L5P platform, this race exhaust is intended for off-road and competitive use only. Always follow local and federal regulations before installation.
