Maximize Your Duramax's Exhaust Flow

It's no secret that a high-flow exhaust system is the key to unleashing the ultimate performance of your 2011-2019 GM 6.6L Duramax. Fortunately, MBRP offers the perfect option for performance enthusiasts with their 4in Filter Back Single Side, crafted from T304 stainless steel. This high-flow exhaust system is engineered to significantly improve exhaust flow, allowing your Duramax to breathe easier and work more efficiency. By reducing exhaust backpressure, this system keeps your engine running at lower exhaust temperatures, which is critical for maintaining engine health and longevity. The benefits are immediately noticeable; expect a boost in fuel effeciency, torque, and horsepower. And let's not forget about the sound. MBRP is known for delivering that unmistakable, deep, throaty growl. This 4in Filter Back Single Side Exhaust System features their signature Tour Profile, allowing you to enjoy that iconic aggressive sound without the obnoxious volume. This is the sound your GM truck should've had straight out of the factory.

Protected by Lifetime Warranty

MBRP built this 4in Filter Back Single Side to endure anything you put your 6.6L Duramax through, from towing heavy loads to ripping around on the race track. Built from mirror-polished T304 stainless steel, this exhaust system not only adds an aesthetic touch to your GM truck but also offers a host of functional benefits. T304 stainless steel offers superior corrosion resistance, heat resistance, chemical resistance, and overall strength over traditional stainless steel. Additionally, getting back on the road is remarkably quick and painless, as this premium exhaust system features a bolt-on installation process. To protect your investment, MBRP protects this product with their industry-leading Lifetime Warranty.
