Exhaust system with DPF and CAT 4" Downpipe-Back removal

Suitable for 2001, 2002, 2003, 2004, 2005, 2006, 2007 Chevy / GMC Duramax Diesel. Silverado and Sierra pickup trucks. Crew cab short bed and crew cab long bed. Not suitable for commercial Cab & Chassis trucks.

Exhaust material - comes in aluminized steel or stainless steel T-409. Aluminized steel is the most popular, but rust develops over time. T-409 stainless steel. Unlike stainless steel T-304, it 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. We recommend using stainless steel if you run your truck regularly on salty winter roads. Use the drop down menu to make your desired selection.

Installation - Installation takes about 1 hour using basic hand tools on your driveway or garage lot. 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. If you don't already have a tuner with DPF removal capability, we recommend the H&S Mini Maxx.
