Make Your Duramax Sound As Strong As It Looks

With polished 304 stainless tubing and a black ceramic-coated tip, it doesn’t just perform better, it looks the part, too. This system gives your truck a clean, deep tone that stands out without being overbearing, making it perfect for daily drivers who still want to turn heads. You’ll notice quicker throttle response and a smoother feel when climbing hills, passing on the highway, or towing a trailer. Plus, the free-flowing design helps your turbo spool faster and reduces unnecessary back pressure. It installs easily with no cutting or welding and uses your factory hanger locations, so you can bolt it up in your own garage. If you’re ready for better sound, sharper looks, and performance you can feel, this is the exhaust to make it happen.

Built With Flow Efficiency And Real Durability In Mind

This DPF-back system from PPE is more than a style upgrade, it’s engineered to handle the demands of daily use, towing, and long-term durability. The 4-inch mandrel-bent tubing is made from 304 stainless steel, chosen for its resistance to corrosion, road salt, and extreme temperatures. The smooth interior bends help reduce flow restrictions, which leads to improved turbo response and more efficient exhaust gas evacuation. Interlocking stainless steel bellows give the system flexibility where it needs it most, allowing for thermal expansion and vibration without fatigue or cracking. It bolts directly to the factory exhaust path after the DPF, keeping emissions equipment untouched and fully functional. The black ceramic-coated tip isn’t just for show, it also resists discoloration and high-heat damage over time. With included stainless clamps and no welding required, it’s designed for a hassle-free installation that holds up in tough conditions.
