Eisenmann Race Center Pipes without Resonator (Full Sound) - F8X M3/M4
Straight pipe center section without a resonator for the most volume
Eisenmann has engineered the F8X M3/M4 exhaust to use this center section as an option. The factory M3/M4 section 2 system uses a resonator and dual catalytic converters 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 a large center section - from the downpipes to just in front 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.
