Vehicle Fitment

This stainless steel 4" 2015.5-2016 GM DPF Delete Pipe is built specifically for 2015.5-2016 GMC and Chevy Duramax 6.6L 2500/3500 pickups. It fits only models with the OEM-style 3-bolt flange on the turbo direct pipe. You must perform race tuning after installation to ensure the system operates correctly. Additionally, this kit does not fit Cab & Chassis trucks, so always verify vehicle compatibility.

Performance & Application

The 4" race pipe fully removes the catalytic converter and DPF filter, which significantly enhances exhaust flow for off-road use. Crafted from high-quality stainless steel, this pipe withstands harsh racing conditions, ensuring durability and performance. Since this pipe is optimized for competition, tuning your engine for the increased airflow becomes necessary, further boosting vehicle performance.

Key Features

Engineered to deliver maximum flow, this 4" pipe improves exhaust efficiency under extreme conditions. The OE-style hangers allow for straightforward installation by securing the pipe firmly. Lacking bungs, the pipe is suitable for off-road use only. If you wish to manage sound levels, you can add a 4" muffler.

• Improves exhaust flow for better performance

Installation Considerations

Since this system involves removing emission components, you must rely on professional installation and race tuning. The 2015.5-2016 GM DPF Delete Pipe is designed strictly for off-road environments. Using this pipe on public roads may lead to legal issues and affect performance.
