As Eisenmann GmbH approaches the end of the research and development stage of any exhaust system, final tests are conducted to ensure perfect fitment and function of the new design.
Eisenmann technicians dyno test the prototype exhaust system to ensure that the flow improvement predicted in their CAD modeling shows itself in the real world, and use acoustic testing and waveform analysis to check the sound output of the exhaust system.
Eisenmann’s testing and development equipment allows the engineers to simulate exhaust pulses through test mufflers before a real car is ever run on their dyno, but nothing is as accurate as real world testing. For this, Eisenmann’s microphones allow them to do acoustic sampling and advanced wave form analysis to not only detect but also tune out unwanted sound frequencies.
Finally, Eisenmann uses a Zeiss FaroArm to rescan the finished exhaust system, in order to verify that the production system is millimeter to millimeter the same size as the exhaust system originally designed by Eisenmann’s engineering team. This allows Eisenmann to verify their fabrication jigs and create an exhaust that is a perfect fit, every time.

BMW’s 1M is a car many people thought would never come. The 1M was a car meant to recapture a spirit lost in the glorious era of 1980’s homologation, and although it is not a true race-bred homologation special it is by 21st century standards a no-nonsense driver’s car. BMW enthusiasts have been asking for a simpler and most importantly slimmer sports car throughout the 2000s as the M3 and M5 have gained weight and sophistication and BMW has finally answered their call with the amazing 1M.
The car is interactive, simple, relatively low in weight, and incredibly fun to drive so it should come as no surprise that BMW chose to couple the 1M with the forever iconic E30 M3 in their marketing campaign for their new sports coupe.
Eisenmann GmbH answers the call of BMW enthusiasts by adding their one of a kind roar to the 1M’s already engaging personality. Eisenmann’s engineers are currently in the process of developing a complete downpipe-back exhaust system for the 1M in both a Race and Sport variation that will give the 1M the sound it deserves. Each Eisenmann system will feature four aggressive 90mm tips, a choice of a silenced or straight through intermediate pipes, and Eisenmann’s unique hand built construction.
