Eisenmann has engineered the F12/F13 M6 exhaust to use this center section as an option. The factory M6 section 2 system uses a resonator to tone down the exhaust volume even more. By removing this factory resonator with a set of straight pipes, more exhaust volume can be heard. It's like turning the volume knob up a few clicks.
As with their mufflers, the Eisenmann center pipes are made from T304/T306 stainless steel. This is the complete center section - from the headers to just ahead of the rear muffler - and uses all of the factory hangers, gaskets, and hardware. The bolt/slip-on design makes this an easy upgrade to the Eisenmann muffler at any time so you can try out the muffler first and if you desire more sound the center section can be added later.
With near-zero restriction in the piping a small power gain may come from this section, especially on turbo cars, but the real purpose is to increase sound levels. The Eisenmann pipes will also save some weight over the factory section.
This exhaust section is built to order and ships from Eisenmann's factory in Germany. Please allow 6-8 weeks for production and shipment.
Note: This exhaust system is designed to change the tone and increase the volume of the exhaust. Some states or jurisdictions have strict sound regulations that prohibit any changes to the factory exhaust. It is the responsibility of the vehicle owner to ensure his/her vehicle complies with all federal, state, county, or local regulations. Installation of this exhaust will not increase emissions nor cause a check-engine light or fault codes on a properly maintained vehicle. It was developed to work with all factory emissions controls and equipment.
