The MBRP Armor Pro Series cat-back exhaust system is engineered for enthusiasts who demand the highest level of durability and performance. Constructed from T304 stainless steel, this 2.5-inch mandrel-bent system is built to withstand extreme environmental conditions while delivering a significant 24% increase in exhaust flow. By reducing backpressure and rippling in the bends, this system helps lower exhaust gas temperatures and improves throttle response.

This quad rear-exit design is specifically engineered to clear the Audi Sport Differential, ensuring a perfect fit for high-performance submodels. To maintain vehicle electronics, MBRP includes electronic valve simulators that allow for the removal of the factory exhaust valves without triggering a check engine light. The system is a direct bolt-on upgrade that utilizes the factory hanger locations and is finished with premium carbon fiber tips for a distinct, high-end look.
