A Clean Contrast That Brings Out Your Trucks Personality

The PPE DPF-Back Performance Exhaust Kit is a strong upgrade for 2023-2025 Duramax owners who want better performance with a bold but refined look. The polished stainless tubing paired with black ceramic coated quad tips creates a sharp contrast that looks intentional and high-end. On the road, the truck feels more responsive, especially when accelerating or pulling through long highway grades. The exhaust note is deeper and smoother, adding presence without becoming overwhelming during daily driving. Retaining the factory exhaust valve keeps things calm at cruising speeds and opens up naturally when you get into the throttle. It is the kind of upgrade that makes the truck more enjoyable to drive while elevating its rear-end appearance.

Designed To Improve Flow Without Sacrificing Fitment

This DPF-back exhaust system replaces the factory muffler-equipped exhaust from the exhaust valve back to the tailpipe. It is constructed entirely from mandrel bent four-inch 304 stainless steel tubing for excellent corrosion resistance and long-term durability. By eliminating the restrictive factory muffler, the system reduces exhaust back pressure to improve turbo efficiency and throttle response. Factory hanger locations are reused to maintain proper alignment and fitment once installed. Installation does require cutting the factory exhaust, which should be planned for ahead of time. Built specifically for 2023-2025 GM 1500 Sierra and Silverado trucks with the 3.0L Duramax, this kit includes 304 stainless steel clamps and is backed by a limited lifetime warranty on the stainless exhaust components.
