A Clean Performance Upgrade With A Refined Finish

The PPE DPF-Back Performance Exhaust Kit is a great option if you want your 3.0L Duramax to feel more responsive while keeping a clean and understated look. The raw stainless tubing paired with polished quad tips gives the rear of your truck a subtle performance vibe without being flashy. On the road, throttle response feels sharper and the engine pulls more freely, especially during highway passing and steady climbs. The sound gains a deeper tone that feels confident but never harsh, making it easy to live with every day. Because the factory exhaust valve is retained, the truck stays quiet when cruising and opens up naturally under load. It is the kind of upgrade that improves how the truck drives while adding a tasteful visual upgrade out back.

Built To Improve Flow While Retaining Factory Function

This DPF-back exhaust system replaces the factory exhaust from the diesel particulate filter to the tailpipe, improving overall flow without altering emissions components. It is constructed from mandrel bent 304 stainless steel tubing, offering excellent durability and resistance to corrosion in all driving conditions. The system eliminates the restrictive factory muffler to reduce back pressure, helping improve turbo efficiency and engine response. Raw stainless tubing provides a rugged look while maintaining long term strength and heat resistance. All factory hanger locations are used, allowing for a straightforward installation with no cutting or fabrication required. Designed specifically for 2020-2022 GM 1500 Sierra and Silverado trucks equipped with the 3.0L Duramax, this kit includes all necessary clamps and hardware for a proper install.
