Description

Increase exhaust flow and turbo efficiency on your 6.6L Duramax-powered HD truck with the MBRP 3-Inch Armor BLK Turbo Downpipe. Designed to replace the restrictive factory downpipe, this upgrade helps reduce exhaust backpressure and supports improved throttle response and diesel performance. Constructed from black-coated aluminized steel, it provides durability, corrosion resistance, and a clean under-vehicle appearance. This direct-fit downpipe is engineered for 2011–2015 GM HD applications and is backed by MBRP’s 1-year warranty.
