Description
Upgrade your BMW G8x M3/M4 with the MAD Axle Back Exhaust system and experience a remarkable transformation in sound and performance. This exhaust system is specifically designed to unleash the full potential of the S58 engine, providing an exhilarating driving experience with enhanced sound quality and increased power.
Key Features
-
Enhanced Sound Quality: Transform the exhaust note of your BMW with a deeper and more resonant tone, eliminating the stock rasp while enhancing the S58 engine's signature roar. This exhaust system delivers a rich and aggressive sound without overwhelming cabin noise.
-
Increased Flow and Performance: With a larger tubing diameter of 76mm compared to the stock 70mm, this exhaust system reduces backpressure, promoting smoother exhaust flow. Expect gains of up to +5 HP and +5 lb-ft of torque, resulting in improved acceleration and throttle response.
-
Versatile Exhaust Modes: The valved design allows you to switch between a subdued tone during low-speed cruising and an aggressive, near-straight pipe sound at high loads. Retaining the stock exhaust valve actuators ensures seamless operation through the M-drive settings, providing full control over your car's sound profile.
-
Quality Construction: Crafted from 100% T304 stainless steel, this exhaust system is built for durability and corrosion resistance. TIG-welded for superior strength, it features a meticulous brush-finish for a sleek, polished appearance.
-
Seamless Integration: Engineered 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 fit perfectly within the factory cut-outs, enhancing the vehicle's aesthetics with an OEM+ look.
-
Optimized for Performance: Drone-abatement technologies effectively reduce cabin resonance, ensuring a pleasurable driving experience without intrusive noise. Whether cruising on the highway or tackling twisty backroads, this exhaust system offers a harmonious blend of performance and comfort.
