MAD BMW M3 M4 G8x S58 Axle Back Exhaust

MAD BMW M3/M4 G8x S58 Axle Back Exhaust Unleash the full potential of your G8x M3/M4 with the MAD Axle Back Exhaust system, designed to elevate both the sound and performance of BMW’s iconic S58 engine. Engineered with precision and passion, this exhaust system ensures your driving experience is as exhilarating as it is distinctive.

Key Features: Enhanced Sound Quality: Say goodbye to the stock rasp and hello to a deeper, more resonant tone. The MAD Axle Back Exhaust is crafted to provide a rich, aggressive exhaust note that embodies the spirit of performance, enhancing the S58’s inherent roar without overwhelming cabin noise. Increased Flow and Performance: With a larger tubing diameter of 76mm (compared to the stock 70mm), this system reduces backpressure and promotes smoother exhaust flow, resulting in noticeable gains in horsepower and torque. Expect a robust performance boost, with up to +5 HP and +5 lb-ft of torque, enhancing both acceleration and throttle response. Versatile Exhaust Modes: Featuring a valved design, the MAD exhaust system allows you to switch between a subdued, deep tone during low-speed cruising and an aggressive, near-straight pipe sound at high loads. The stock exhaust valve actuators are retained, ensuring seamless operation via the M-drive settings, giving you control over your car’s sound profile. Quality Construction: Built to last, the entire system is made from 100% T304 stainless steel, ensuring durability and resistance to corrosion. TIG-welded for superior strength and visual appeal, the exhaust system is meticulously brush-finished, offering a sleek, polished look right out of the box. Seamless Integration: Designed for a factory-like fit, the MAD Axle Back Exhaust includes all necessary mounting hardware for easy installation. The quad 4-inch (100mm) clamp-on tips are engineered to fit perfectly within the factory cut-outs, enhancing the car’s aesthetics with a refined, OEM+ appearance. Optimized for Performance: The system’s drone-abatement technologies effectively reduce cabin resonance, providing a pleasurable driving experience without intrusive noise. Whether you’re cruising on the highway or tackling twisty backroads, the MAD exhaust ensures a harmonious blend of performance and comfort.
