Eisenmann has engineered the E46 M3 exhaust to use this center resonator as an option. This center section with the resonator is for the small group of our customers that want to fine-tune their exhaust level, perfect for adding back a resonator if you had a straight pipe. It's a free-flow design, similar to the stock factory resonator but lighter.
As with their mufflers, the Eisenmann center pipes are made from T304/T306 stainless steel. This is a tuned center resonator, replacing the stock piece, and must be cut and clamped or welded onto the original exhaust.
This exhaust section is built to order and ships from Eisenmann's factory in Germany. Because of the COVID impact, delivery times have been as long as 10-12 weeks after ordering but could be shorter. For the latest ETA info please contact our sales team.
Notice of Regulatory Non-Compliance. This exhaust system has been developed to work in conjunction with all factory emissions controls and equipment. Installation of this exhaust will not increase emissions nor cause a check-engine light or fault codes on a properly maintained vehicle. However, neither BimmerWorld nor the manufacturer can assure compliance with local or state regulations regarding sound levels or other compliance with vehicle inspection or registration. It is the responsibility of the vehicle owner to ensure his/her vehicle complies with all federal, state, county, or local regulations. Some suppliers will not ship to certain states, requiring extra delivery time. We will advise you of any delays.
