TAG Motorsports is pleased to offer the Eisenmann Non-Resonated Center Pipe Set for the BMW G80 M3 / G82 M4 (2021+).

While BMW’s S58 engine is a substantial improvement over the S55 in the sound department, the factory G8X M3 and M4 center pipe section still leaves plenty of room for improvement. The factory center pipes contain both a pair of secondary catalytic converters and two large resonators, creating unnecessary restriction, added weight, and a more subdued exhaust character.

The Eisenmann G8X M3 / M4 Center Pipe Set is designed to improve exhaust flow, reduce weight, and unlock a more engaging sound profile from the S58 platform. Compared to the resonated Eisenmann center pipe set, the factory center pipe assembly is approximately 10 pounds heavier, making this upgrade a meaningful improvement for enthusiasts looking to reduce mass while enhancing exhaust tone.

Eisenmann center pipes are designed to pair directly with the Eisenmann Performance Exhaust System for the BMW G8X M3 and M4, but they can also be installed with the factory rear muffler section. Available in either resonated or non-resonated configurations, the center pipe set allows the Eisenmann G8X rear exhaust to be converted from a European-style slip-on installation into the fully bolt-on configuration that many U.S. enthusiasts prefer.

For owners retaining the factory rear muffler, the non-resonated center pipe set includes an X-pipe in place of the resonator to further tune exhaust gas flow and increase sound presence. This configuration offers a cost-effective way to create a much more aggressive exhaust note while also reducing weight compared to the factory center section.

For those seeking an additional visual and functional upgrade, the optional Black Series finish features a high-temperature ceramic coating engineered to improve heat dissipation and provide superior corrosion resistance.

Eisenmann has been handcrafting exhaust systems in Germany for over 30 years and serves as an OE supplier to some of the world’s leading automotive manufacturers. That experience is reflected in the quality, sound, and finish of every Eisenmann performance exhaust system.
