Description
The MBRP 2017–2026 Chevrolet Silverado & GMC Sierra 2500HD/3500HD 6.6L Duramax L5P 3.5" Black Down Pipe is a premium performance upgrade engineered to maximize exhaust flow, improve turbocharger efficiency, and enhance the overall performance of your Duramax-powered truck. Designed specifically for the 6.6L L5P Duramax diesel engine, this downpipe replaces the restrictive factory component to provide smoother exhaust flow and improved engine responsiveness.
Manufactured from heavy-duty aluminized steel and finished with a durable high-temperature black coating, this downpipe is built to withstand harsh operating conditions while offering excellent corrosion resistance and long-lasting durability. The 3.5-inch mandrel-bent tubing maintains a consistent diameter throughout the pipe, minimizing turbulence and reducing exhaust backpressure for optimal performance.
By increasing exhaust flow, the MBRP downpipe helps the turbocharger spool more efficiently, resulting in quicker throttle response, improved turbo performance, and lower exhaust gas temperatures (EGTs). These benefits make it an ideal upgrade for daily driving, towing, hauling, and high-performance diesel applications.
Designed as a direct-fit replacement, the downpipe installs using factory mounting locations for precise fitment with minimal modifications, depending on the vehicle's configuration.
