4" DPF & CAT delete pipe allows you to remove the factory diesel particulate filter & catalytic converter. Bolts directly to the factory turbo-direct. Fits Chevy/GMC 2500 & 3500 pickup trucks. WILL NOT FIT regular cab or Cab & Chassis trucks. Installation takes approx. 1hr, cutting may be required. 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. We recommend the EZ Lynk. Expect to increase fuel mileage 3-4 mpg. More or less depending on how plugged up your 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.
The 2015.5-2016 downpipe is secured using a 3 bolt flange. Be sure to verify the clamp style your truck is equipped with.
