The MagnaFlow 19694 Pro DPF Series system replaces the exhaust piping on 6.6L Duramax-equipped Chevrolet Silverado and GMC Sierra 2500/3500 HD trucks from behind the factory diesel particulate filter back to the tip. It gives owners of these heavy-duty diesel trucks a mandrel-bent, larger-diameter piping path to reduce backpressure while leaving the factory DPF, SCR system, and emissions controls untouched and fully functional.

MagnaFlow 19694 Compatibility Notes:

• 5 in. mandrel-bent aluminized and stainless steel piping mounts behind the factory DPF outlet using a clamp-on connection.
• Single passenger-side rear exit with an intercooled, polished stainless steel tip finishes the installation.
• Does not affect the factory diesel particulate filter, selective catalytic reduction system, or any OEM emissions equipment.
• Hangers are included to mount the system at the factory hanger locations.

Emissions Note:

This part is legal for sale or uses on Emissions Controlled Vehicles, Uncontrolled (Non-Emissions Controlled) Vehicles, and Racing Use Only Vehicles because it does not affect vehicle emissions and is not covered by emissions regulations.
