MagnaFlow 15 BMW M3/M4 L6 3.0L SS Cat-Back Perf. Sport Quad Split Rear Exit Exht - 3.5in Black Tips

Magnaflow is well-known for creating exhaust systems that offer a distinct sound and improved flow. This Sport Series cat-back system, part number 19187, is specifically made for your 2015-2020 BMW M3 or M4 with the L6 3.0L engine. It replaces your stock exhaust from the catalytic converter back, aiming to give your car a more aggressive character and a sound that stands out.

The system features 2.5-inch diameter, mandrel-bent main piping designed for fast flow, leading to two straight-through mufflers. It exits in a quad split rear configuration with 3.5-inch black-coated, welded double-wall tips that are angle-cut and folded. This setup is dyno-proven to enhance performance, producing an aggressive exterior sound while aiming for a moderate interior level. It's important to check local noise regulations to ensure compliance.

Constructed from durable, corrosion-resistant stainless steel, this cat-back system is built to last. Magnaflow uses extensive 3D scanning and CNC precision robotic manufacturing to ensure a perfect fit, making installation straightforward. The system comes with a 1-year finish warranty and a limited lifetime construction warranty from Magnaflow.
