4" pipe for DPF and CAT removal

Vehicle compliance - 2017, 2018, 2019, 2020, 2021, 2022 and 2023 Chevy / GMC Duramax Diesel L5P. Silverado and Sierra pickups. Short bed crew cab and long bed crew cab. Not suitable for 3500/4500/5500 Cab & Chassis commercial type trucks.

Exhaust material is made of aluminized steel or T409 stainless steel. Common misconception: unlike T304 stainless steel, T409 stainless steel is still magnetic. So if you are checking to see if you really have stainless steel, keep in mind that the magnet will still stick to it.

Installation - Installation takes about 1 hour using basic hand tools on the ground of your driveway or garage. Faster if you have a car elevator. A trim may be required for installation on a shorter wheelbase. Clamps, hangers, and fasteners are included. You may have to reuse some of the factory fasteners.

Fuel mileage - Expect a significant increase in fuel mileage. If your DPF is clogged, you probably average about 13-14 miles per hour. More or less depending on the degree of clogging. After removing the DPF/CAT, expect a combined mileage of 18-19 mpg. Big tires and poor driving habits will result in lower mileage.

Tuner required - Removal of DPF, CAT, SCR and/or DOC includes removal and elimination of emission related sensors. A tuner with DPF removal capability is required to prevent engine warning lights or diagnostic trouble codes.
