A Clean Side Exit That Wakes Up Your Daily Drive

The PPE DPF-Back Performance Exhaust Kit is a great fit for 2023-2025 Duramax owners who want better response without going overboard on sound. The single side-exit layout keeps things simple and purposeful while adding a noticeable performance edge. From behind the wheel, the truck feels more eager to move, especially when accelerating from a stop or rolling into the throttle on the highway. The exhaust note is deeper and smoother, giving the Duramax a confident tone that stays comfortable for everyday driving. The polished oval side-exit tip adds a clean finishing touch that looks sharp without drawing too much attention. It is an ideal upgrade if you want improved drivability with a subtle performance look.

High Flow Design Built Around Factory Integration

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 corrosion resistance. By eliminating the restrictive factory muffler, the system reduces exhaust back pressure to improve turbo efficiency and throttle response. The exhaust retains factory hanger locations and the factory exhaust valve to maintain proper operation and fitment. Installation does require cutting the factory exhaust, which should be considered before starting the job. Designed specifically for 2023-2025 GM 1500 Sierra and Silverado trucks with the 3.0L Duramax, this kit includes all necessary hardware and is backed by a limited lifetime warranty on the stainless exhaust components.
