Experience the thrill of driving with the MAD BMW M340 M440 Catback Exhaust, a top-of-the-line performance upgrade designed to elevate the driving dynamics of your BMW M340 or M440 to new heights. Crafted with precision engineering and a passion for performance, the MAD Catback Exhaust is the ultimate choice for automotive enthusiasts seeking superior power and sound.

Engineered to perfection, the MAD Catback Exhaust unleashes the true potential of your BMW M340 or M440. The catback design optimizes exhaust flow, reducing backpressure, and enhancing engine performance. As you accelerate, you'll be greeted with an aggressive yet refined exhaust note that announces your presence with authority.

The MAD BMW M340 M440 catback exhaust system is a statement in refined power and acoustics. Engineered with meticulous attention to detail, this exhaust system redefines the sound and performance of your BMW M340 or M440.

One of the standout features of this exhaust system is that it reuses the stock tips, providing a seamless integration with the aesthetics of your BMW. The system is a full catback, designed to offer the richest sound possible, turning every drive into an exhilarating experience.

Installation is a breeze with no cutting required. This system is 100% plug and play, making it a completely reversible modification if you ever wish to return to the stock exhaust.

Constructed entirely from 304 stainless steel, this exhaust system is as durable as it is striking. The larger diameter piping enhances the flow, promoting superior performance and a sportier, more enjoyable sound.

The stock exhaust valve actuator is repurposed and an additional valve/actuator is integrated on the opposing side to ensure even flow, regardless of the valve position. The computer-controlled exhaust valves are retained to limit noise during low speed driving while fully opening under high-load conditions, ensuring the perfect balance between sound and performance.

Included with the exhaust system is easy-to-follow, bolt-on installation hardware. This makes the MAD BMW M340 M440 catback exhaust system a transformative addition to your vehicle that is not only impactful in performance, but also simple to implement.
