Overview
Built for 2011–early 2015 Chevrolet Silverado and GMC Sierra 2500HD and 3500HD pickups with the 6.6L Duramax LML engine, this 4-inch stainless steel DPF race pipe is designed for trucks equipped with the factory V-band turbo outlet connection. It provides a replacement exhaust section for dedicated off-road and competition applications, using durable stainless steel construction and OE-style hangers for secure mounting.
Have a late 2015 or 2016 Duramax LML with a 3-bolt turbo outlet flange?
This V-band race pipe will not fit your truck. View the 2015.5–2016 Duramax LML DPF Race Pipe (3-Bolt Flange) for the correct configuration.
Vehicle Fitment: 2011–Early 2015 Duramax LML
- Make: Chevrolet and GMC
- Models: Silverado 2500HD, Silverado 3500HD, Sierra 2500HD and Sierra 3500HD
- Engine: 6.6L Duramax LML turbo diesel

Important: V-Band vs. 3-Bolt Turbo Outlet Flange
The Duramax LML exhaust connection changed during the 2015 production period. The correct race pipe depends on the factory turbo outlet flange, not simply the truck's model year.
| Model Years | Turbo Outlet Connection | Correct Pipe |
|---|---|---|
| 2011–Early 2015 | Factory V-band clamp connection | This pipe is correct for that configuration. |
| Late 2015–2016 | Factory 3-bolt turbo outlet flange | These trucks require the late-style pipe. |

Installation and Tuning Requirements
Compatible race-specific engine calibration is required for the intended competition application. Professional installation is recommended to verify flange fitment, exhaust alignment, hanger placement and clearance around nearby components.
Before Installation
- Confirm that your truck has the factory V-band turbo outlet connection.
- Verify pickup configuration, bed length and wheelbase compatibility.
- Confirm that the existing exhaust can be modified as required.
- Arrange appropriate professional installation and competition-specific tuning.
- Check whether additional exhaust components are required for your setup.
Optional 4-Inch Diesel Muffler
Want to reduce exhaust noise in your race exhaust setup? A compatible 4-inch diesel muffler can help manage sound while maintaining a straight-through exhaust configuration. Mufflers are available separately and are not included with this pipe.
