Upgrade your 2023-2025 GM 3.0L Duramax LZO with the PPE Stainless Steel DPF-Back 4" Exhaust Kit with a 5.5" oval tip for better performance, fuel efficiency, and a deeper, more aggressive sound.
Say goodbye to the restrictive factory muffler and inferior 409 stainless steel. This free flowing exhaust system is built from premium 304 stainless steel, ensuring lasting durability and superior corrosion resistance. The mandrel-bent 4” tubing reduces back pressure at the manifolds, improving turbo efficiency, throttle response, and fuel economy. Designed for an easy single cut and bolt-on installation, this kit utilizes factory hanger locations, retaining the stock exhaust valve and includes all necessary hardware for installation. Available in raw or polished finishes, it comes with a 5.5” oval tip, offered in ceramic-coated black or polished stainless steel for a custom look.
This exhaust system delivers better throttle response, improved fuel economy, and the performance your truck deserves.
