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.


 Key Features

  • Built with 16-gauge T409 stainless steel for long-term durability
  • Mandrel-bent tubing for maximum flow and performance gains
  • Leak-free flanges and TorcTite® clamps for a secure connection
  • Includes contour bent hangers to ensure factory-style fit
  • Designed to lower EGTs and improve throttle response
  • Signature DIESELR sound – deep, aggressive tone
