Description

This 3.5" Down Pipe replaces the restrictive crushed factory downpipe/front pipe on 2017-2026 L5P 6.6L Duramax-equipped Chevrolet Silverado or GMC Sierra 2500/3500 HD trucks for improved exhaust flow. It features fabricated steel construction and a black high-temp ceramic coating with heat wrap for thermal protection. The downpipe includes bungs for sensors and connects to the DOC (Diesel Oxidation Catalyst) outlet flange, mating with the OEM exhaust system front pipe using a 4-bolt style flange connection. No tuning is required. It replaces GM Part Number 12671086. WCFab piping kits and emissions-compliant tuning are recommended for optimum performance gains.
