In need of a full L5P race package.

4′ and 5″ Downpipe-Back DPF & CAT delete exhaust system.

Vehicle fitment – 2017, 2018 & 2019 Chevy / GMC Duramax Diesel L5P. Silverado and Sierra pickup trucks. Crew cab short bed & crew cab long bed. This will not fit the 3500/4500/5500 Cab & Chassis commercial style truck.

Exhaust Material  Available in aluminized steel or T-409 stainless steel. Aluminized steel is our most popular but will eventually accumulate surface rust. T-409 stainless steel. Unlike T-304 Stainless its still magnetic. So if your testing to see if you actually got stainless; beware that a magnet will still stick to it. We suggest the stainless upgrade if you regularly operate your truck on salted winter roads. Use drop down menu to make desired selection.

Installation – Install takes approx. 1hr with basic hand tools done on the ground of your driveway or garage. Quicker if you have automotive style lift. Cutting may be be required to fit shorter wheelbase bed/cab configurations. Clamps, hangers and hardware are included. You may have to re-use some factory hardware.

Fuel Mileage – Expect to see a significant increase in fuel mileage. If your DPF is plugged up your probably averaging about 13-14 mpg. More or less depending on the severity of the restriction. After deleting the DPF/CAT expect to get a combined mileage of 18-19 mpg. Larger tires and poor driving habits will skew mileage downward.

Tuner Required – Removal of the DPF, CAT, SCR, and/or DOC involves removing and eliminating emission related sensors. A DPF delete capable tuner is required to prevent any check engine light or diagnostic trouble codes from setting. If you don’t already have a DPF delete capable tuner we recommend Our Kit

If you need multiple exhausts add to cart separately
