Vehicle Fitment
The 6.6L Duramax LML DPF Delete Pipe fits 2011 to 2015 Chevrolet Silverado and GMC Sierra 2500 & 3500HD models with the 6.6L Duramax engine. It is important to note that this pipe does not fit Cab & Chassis models, and late 2015 models with a three-bolt flange are incompatible.
Performance Enhancement
This race pipe removes the catalytic converter and DPF filter, boosting exhaust flow to enhance off-road performance. Its stainless steel construction offers exceptional durability. The included OE-style hangers ensure that you can install the pipe smoothly. Additionally, race tuning is required, allowing your vehicle to achieve improved power and optimized exhaust performance.
Durable Build
The Duramax 6.6L DPF Delete Pipe, made from tough stainless steel, withstands harsh racing environments. The OE-style hangers secure the exhaust in place, ensuring it remains stable even during aggressive driving.
Installation Guidelines
Modifications to the factory exhaust are necessary to install this pipe, as it requires cutting the current system for a proper fit. Since the product includes no bungs, it is suitable only for off-road use. Professional tuning is necessary to ensure optimal performance and prevent issues like check engine lights.
