A Polished Side Exit That Elevates Everyday Driving

The PPE DPF-Back Performance Exhaust Kit is a great fit for 2023-2025 Duramax owners who want noticeable gains without giving up refinement. From the first drive, the engine feels more responsive, especially when pulling onto the highway or easing into the throttle around town. The sound is deeper and smoother, adding character without becoming loud or tiring on long trips. The single side-exit layout keeps the look clean and practical, while the polished oval tip and polished tubing add a premium finish. Retaining the factory exhaust valve helps maintain a calm tone during cruising and opens things up naturally when needed. It is an upgrade that makes the truck feel better to drive while giving it a subtle but upscale performance look.

High Flow Stainless Construction With Factory Friendly Design

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 durability and resistance to corrosion. Removing the restrictive factory muffler helps reduce exhaust back pressure, improving turbo efficiency and overall engine response. The system uses factory hanger locations and retains the factory exhaust valve to ensure proper fitment and operation. Installation does require cutting the factory exhaust, which should be considered before starting the install. Designed specifically for 2023-2025 GM 1500 Sierra and Silverado trucks equipped with the 3.0L Duramax, this kit includes all required hardware and is backed by a limited lifetime warranty on the stainless exhaust components.
