Eisenmann Racing Center Pipes - E90/E91 325i/328i/xi
German-made E90/E91 325i/328i/xi straight midpipe for maximum sound
Eisenmann has engineered the E90/E91 325i/328i exhaust to use this center section as an option. It covers the center section from the headers to just in front of the factory muffler. The factory E9X mid-section uses a pair of catalytic converters and a resonator to tone down the exhaust volume even more. By removing these factory features with a set of straight pipes, more exhaust volume can be heard as well as eliminating a set of cats that are unnecessary and a liability for track use.
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 in front of the rear muffler. The bolt/slip-on design makes this an easy upgrade for use with an Eisenmann muffler or to build a custom rear muffler for track use (single inlet).
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.
