Cat & DPF Race Pipe (2011-2015 GM 2500/3500 6.6L Duramax)

The DIESELR Race Pipe Duramax LML V-band is built to handle extreme duty for 2011–2015 GM 2500/3500 HD trucks equipped with the 6.6L Duramax engine. This off-road exhaust system replaces the factory cat and DPF section with a high-flow, mandrel-bent T409 stainless steel pipe that boosts airflow and reduces EGTs.

This model is specifically engineered for trucks with a V-band clamp at the turbo direct pipe. If your truck is equipped with a 3-bolt flange, this kit will not fit—please verify fitment before ordering.
