2020-2025 Duramax 5" SS Downpipe Back Exhaust System - No Muffler (DDC-5GM20)

Note: Fits all wheelbase and cab configurations unless otherwise specified. Only fits models equipped with the OEM-style 4-bolt flange off the turbo direct pipe. Aftermarket custom tuning is required. Designed for competition/race use only.

The DDC-5GM20 is the perfect kit for replacing your restrictive stock components with high-performance, high-flow 5" piping from the downpipe back. Just like all of our exhaust kits, it comes with all the required clamps, pre-weld contour bent hangers, and reinforced flanges to help you cruise through the installation process. You'll notice improved fuel mileage, increased torque, and a much more aggressive-sounding 6.6L Duramax.
