The ARM 340i Midpipe elevates the sound of your B58, delivering the aggressive exhaust note you've been looking for in a tuned B58-powered BMW. Engineered to boost both power and sound, this midpipe eliminates the two central resonators found in the stock 340i setup. Retaining the OEM muffler allows you to control the exhaust volume—engage Sport Plus mode to unleash the full roar of the upgraded B58, or switch to Comfort mode for a quieter drive through the neighborhood.

Unlock the full potential of your G87 M2’s exhaust with the Eisenmann G87 M2 Center Pipe Set, designed to significantly enhance both sound and performance. While the S58 engine already offers a sound improvement over the S55, the stock center pipes remain a limiting factor. The OEM setup includes secondary catalytic converters and dual resonators, adding unnecessary weight and dampening the exhaust note. Eisenmann’s resonated center pipes, weighing 10 lbs less than the factory version, provide a noticeable upgrade in both weight reduction and exhaust tone.

These center pipes are engineered to integrate perfectly with the Eisenmann Performance Rear Exhaust but can also be installed with the factory rear section, offering flexibility in setup. Available in both resonated and non-resonated configurations, the system converts the European-style slip-on design to the fully bolt-on system preferred by U.S. enthusiasts, ensuring easy installation and a secure fit.

For those who want to keep the stock rear muffler, the non-resonated option features an integrated x-pipe, replacing the bulky resonators. This configuration optimizes exhaust flow, delivering a more aggressive sound while shedding weight. It’s a cost-effective upgrade that enhances performance without requiring a full exhaust system replacement.

Optional Black Series Finish: For added performance and protection, the Black Series Ceramic Coating offers a high-temperature ceramic coating, improving heat dissipation and providing superior corrosion resistance, ensuring long-lasting durability and style.
