Product Details
Introducing the MAD BMW M340 M440 catback exhaust system – a pinnacle of refined power and captivating acoustics. Engineered with meticulous precision, this exhaust system revolutionizes the auditory and performance aspects of your BMW M340 or M440.
One of its notable features is the option to utilize the stock tips, seamlessly blending with your BMW's aesthetics. Alternatively, you can opt for one of our three quad tip configurations, providing a striking quad look (Requires removal of OEM tips or addition of an aftermarket quad diffuser). Crafted as a full catback system, it ensures an immersive driving experience with its rich, resonant sound.
Installation is effortless, requiring no cutting. This system is entirely plug and play, ensuring a reversible modification if you decide to revert to the stock exhaust.
Constructed from robust 304 stainless steel, durability is matched with striking aesthetics. The increased diameter piping optimizes flow, enhancing performance and delivering a sportier, more enjoyable sound.
Utilizing the stock exhaust valve actuator while integrating an additional valve/actuator ensures consistent flow, regardless of the valve position. The computer-controlled exhaust valves remain intact, moderating noise during low-speed driving and opening fully under high-load conditions, striking a perfect balance between sound and performance.
The exhaust system comes with straightforward, bolt-on installation hardware, making it a transformative addition to your vehicle that not only enhances performance but also boasts seamless implementation.
