Description
The MBRP 2015–2016 Chevrolet Silverado & GMC Sierra 6.6L Duramax 3" Black Down Pipe (3-Bolt Flange Connection) is a high-performance exhaust upgrade engineered to improve exhaust flow, turbocharger efficiency, and overall engine performance for 6.6L Duramax diesel-powered trucks equipped with the 3-bolt flange style connection. Designed as a direct replacement for the restrictive factory downpipe, this system delivers increased exhaust efficiency while maintaining OEM-quality fitment.
Constructed from heavy-duty aluminized steel and finished with a durable high-temperature black coating, this downpipe offers excellent strength, corrosion resistance, and long-lasting durability in demanding driving conditions. The 3-inch mandrel-bent tubing ensures smooth, unrestricted exhaust flow by reducing turbulence and backpressure, allowing the turbocharger to spool more efficiently.
By minimizing exhaust restriction, the MBRP Down Pipe improves throttle response, turbo performance, and engine efficiency, while helping to lower exhaust gas temperatures (EGTs). These benefits make it an excellent upgrade for towing, hauling, off-road use, and performance-focused diesel applications.
Specifically designed for vehicles with the factory 3-bolt flange connection, this direct-fit downpipe installs using OEM mounting locations for a precise fit with minimal modifications.
