MBRP S4603304 Cat-Back Exhaust System 3 Inch Quad Split T304 Stainless Steel

The MBRP S4603304 Armor Pro Series cat-back exhaust system is engineered to deliver exceptional performance and sound for the Volkswagen Golf R MK7 and MK7.5 models. This precision-crafted exhaust system features a 3-inch diameter design with quad split rear configuration, maximizing exhaust flow while maintaining optimal backpressure for improved engine performance.

Premium T304 Stainless Steel Construction

Built from high-grade T304 stainless steel, this exhaust system offers superior resistance to rust, corrosion, and heat degradation compared to lesser materials. Each component is jig-built to exacting tolerances, ensuring precise fitment and long-lasting durability even under demanding driving conditions.

Performance-Engineered Design

The S4603304 utilizes mandrel-bent tubing throughout, eliminating restrictive crimps and maintaining consistent diameter through every bend. This advanced construction delivers up to 24 percent increase in exhaust flow compared to the factory system, supporting enhanced horsepower and torque delivery. The system includes valve delete functionality for unrestricted exhaust flow.

Helmholtz Resonator Technology

MBRP incorporates Helmholtz resonator technology to tune the exhaust note, producing a moderate, aggressive sound that minimizes unwanted drone frequencies during highway cruising. This creates an engaging exhaust tone during acceleration while maintaining comfort during everyday driving.

Premium Finishing Touches

The system includes two 4-inch outer diameter dual-outlet mirror-polished tips that add an aggressive, high-performance appearance to your vehicle's rear fascia. The polished finish complements the Golf R's styling while showcasing the quad-tip configuration.
