MBRP 4" Complete Exhaust System – No Muffler

 

Unleash Performance & Efficiency

Upgrade your 2001-2007 Chevy Silverado or GMC Sierra 2500/3500 Duramax 6.6L with the MBRP 4-inch Complete Exhaust System and experience the power of free-flowing exhaust. Designed with mandrel-bent tubing, this system optimizes airflow, reducing restrictions and boosting overall performance. With up to 18 additional horsepower and 28 ft/lb of torque, you'll notice improved throttle response, increased pulling power, and even a potential 1-2 MPG fuel economy gain.

Premium Build Quality for Long-Lasting Durability

Constructed from heavy-duty aluminized steel, this Performance Series exhaust system provides an excellent balance of affordability and durability. Unlike budget exhausts that suffer from rust at the seams, MBRP uses fully sealed tubing to extend the system’s lifespan. Manufactured to the same high standards as the Pro Series, this kit comes with a 2-Year Warranty, ensuring reliability for years to come.

Enhanced Exhaust Flow & Lower Temperatures

The key to maximizing your Duramax’s performance lies in reducing backpressure. This system is engineered with minimal bend angles and fully mandrel-bent tubing, allowing for faster exhaust flow. As a result, you can experience a reduction in exhaust gas temperatures (EGTs) by up to 200°F, setting the stage for even more gains when paired with cold air intakes, tuners, and other performance modifications.

Easy, Hassle-Free Installation

Designed for a bolt-on, no-weld installation, this exhaust system is as easy to install as it is to enjoy. The kit comes with all necessary clamps and components, and everything is a direct fit to OEM hangers. Most installations can be completed in just 1.5 to 2 hours using standard hand tools, making it an ideal upgrade for DIY enthusiasts.

Aggressive Sound & Bold Styling

MBRP believes performance should sound as good as it feels. This muffler-delete system delivers a rich, aggressive exhaust note, ensuring your Duramax makes a statement on and off the road. Plus, with MBRP’s signature design and stamped logo, this exhaust system enhances both the sound and look of your truck.

Upgrade to the MBRP 4-inch Complete Exhaust System and experience better flow, lower temperatures, increased power, and an unmistakable sound—all in a package built to last.
