5" Downpipe back DPF delete exhaust system allows you to remove the factory diesel particulate filter & catalytic converter on your 2007, 2008, 2009 & 2010 LMM Duramax. It bolts directly to the factory turbo-direct pipe. Fits Chevy/GMC 2500 & 3500 pickup trucks. All necessary pieces to fit the crew cab long bed are included. If you have a short bed or extended cab; cutting may be required. Installation takes approx. 2hrs. Choose between aluminized steel and T409 stainless steel. Aluminized steel is our best seller and the most popular. However, we suggest the stainless upgrade for those who regularly operate there truck on salted winter roads. Removal of the DPF & Catalytic converter involves removing and eliminating emission related sensors. Because of this, when installing a DPF & CAT delete pipe it must also be used with a DPF delete capable tuner. Our most popular DPF delete tuner for the 07-10 Duramax is the H&S Mini Maxx. Expect to increase fuel mileage 3-4 mpg. More or less depending on how plugged up your stock diesel particulate filter is. Typically we see around 18-19 mpg combined mileage. 1 year warranty. Built to order, may take up to 10 days before shipping.
