Product Description

The MBRP S5316409 Cat-Back Exhaust System is a high-quality performance upgrade engineered for Toyota Tundra trucks equipped with 4.6L and 5.7L V8 engines built between 2009 and 2021. Constructed from rugged T409 stainless steel with mandrel-bent 2.5" tubing, this system enhances exhaust flow by reducing backpressure compared to the factory exhaust, helping to improve throttle response, torque, and overall driving performance. Featuring a dual side exit design with polished 3.5" stainless steel tips, it adds an aggressive look and a deep, balanced street sound that's louder and more engaging than stock without being overwhelming on daily drives.

Installation is straightforward thanks to the bolt-on design that uses your Tundra's OEM hanger locations. The rugged T409 stainless construction offers excellent corrosion resistance and long-lasting durability, and the included lifetime limited warranty on stainless components provides added peace of mind. Whether you're cruising around town or hauling heavy loads on the highway, the S5316409 delivers a combination of improved performance, enhanced tone, and refined style for Toyota Tundra owners seeking a high-flow exhaust upgrade.
