Refined Performance That Looks As Good As It Feels

The PPE DPF-Back Performance Exhaust Kit is a great choice if you want your 3.0L Duramax to deliver stronger response while keeping a polished, high-end appearance. From the driver’s seat, the truck feels more eager to accelerate, especially during highway passing and steady towing pulls. The exhaust note gains a deeper, smoother tone that adds character without becoming intrusive on long drives. Polished stainless tubing and quad polished tips give the rear of your Sierra or Silverado a clean, premium look that stands out in all the right ways. Because the factory exhaust valve is retained, the system stays composed during cruising and opens up naturally when you lean into the throttle. It is an upgrade that improves how the truck drives and looks without sacrificing daily comfort.

Engineered For Efficient Flow And Long Term Durability

This DPF-back exhaust system replaces the factory muffler-equipped exhaust from the exhaust valve back to the tailpipe. It is built entirely from mandrel bent four-inch 304 stainless steel tubing for excellent corrosion resistance and long service life. The free-flowing design reduces exhaust back pressure, helping improve turbo efficiency, throttle response, and overall engine performance. Factory hanger locations are retained to ensure proper fitment and alignment once installed. 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 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.
