MAD Axle Back Exhaust for BMW M3/M4 G8x S58

Discover the ultimate upgrade for your BMW M3/M4 G8x S58 with the MAD Axle Back Exhaust system. Engineered to amplify the power and tone of the iconic S58 engine, this exhaust system transforms your driving experience. The MAD Axle Back Exhaust features a larger 76mm tubing diameter for increased flow, providing a robust performance boost with up to +5 HP and +5 lb-ft of torque. Experience the rich, aggressive exhaust note that enhances the S58's inherent roar without overwhelming cabin noise.

Product Specifications and Construction

Crafted from 100% T304 stainless steel, the MAD Axle Back Exhaust boasts exceptional durability and resistance to corrosion. TIG-welded for superior strength, this system also features a sleek, polished look that complements your vehicle's aesthetics. The system is designed for seamless integration, including all necessary mounting hardware and quad 4-inch (100mm) clamp-on tips. This exhaust connects to the factory midpipe (cutting required) or the MAD single midpipe (no cutting required), ensuring compatibility with your vehicle. Specifications include a diameter of 76mm tubing and a weight 7 pounds lighter than the stock axle-back.

Benefits and Practical Uses

The MAD Axle Back Exhaust offers a versatile exhaust mode, allowing you to switch between a subdued, deep tone during low-speed cruising and an aggressive, near-straight pipe sound at high loads. With stock exhaust valve actuators retained, you can easily control your car's sound profile via the M-drive settings. This exhaust system optimizes performance while reducing cabin resonance, ensuring a harmonious blend of comfort and excitement. Whether you're cruising on the highway or tackling twisty backroads, the MAD Axle Back Exhaust delivers a driving experience that is both exhilarating and refined.
