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. 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.

The 2015.5-2016 downpipe on the LML Duramax is secured to the turbo direct pipe using a 3 bolt flange style connection. Be sure to verify the clamp style your truck is equipped with.
