Product Description
4" Stainless Steel DPF Delete Pipe for 2015.5–2016 GMC / Chevrolet Duramax 6.6L 2500/3500
If you’re running a 2015.5–2016 Duramax 6.6L in a 2500 or 3500, this 4-inch DPF delete pipe opens up the exhaust the way it should be for off-road use. It replaces the restrictive factory section and lets the turbo breathe easier, which helps the truck respond quicker under load.
The 2015 LML delete pipe is offered in two variants based on factory turbo outlet flange design.
Selecting the correct version is mandatory for proper fitment:
- 2011–Early 2015 – Uses a V-band clamp at the turbo outlet. (To Buy this product Click Here)
