Eisenmann doesn't quote exact dyno figures, as dyno runs vary too much from run to run. Most dyno technicians I've spoken to have told me "How much power do you want this exhaust to make?" when I talk to them about performing dyno runs, and neither IND nor Eisenmann is interested in doing business that way.
Eisenmann prefers to test system's flow with pressure probes, to test muffler efficiency. You can see the tubes used to output pressure to the test probes in this picture. By testing the amount of backpressure from the OEM system, and then testing the packpressure of the Eisenmann system, they can give a real, repeatable measure of the efficiency of the Eisenmann system. Here are the backpressure measurements: SPORT-Version: moving vehicle = 75 db stationary vehicle = 92 db at 6.225 1/min value of backpressure = -25% weight of the muffler = apr. 21 kg I hope that clears things up a bit! RACE-Version: moving vehicle = apr. 95 db stationary vehicle = apr. 102 db at 6.225 1/min value of backpressure = apr. -32% weight of the muffler = apr. 21 kg

Great choice! I'm really close on deciding to get the Race as well. Probably in the next month or two. Would love to see a vid.

Hey Nate...Im located here in Germany and was wondering if the tour was open to the public or just dealers? Also, if I buy the Race would I be able to get it installed there?

We were scheduled to dyno at Fall-Line, but they've been extremely busy with their Grand Am schedule. We're heading over there for some dyno runs and a full photo tour of their facilities as soon as they have a break in their racing work!

Thanks! I see that you sell Kelleners Sport. Great product. You should post some photos of Ralf's race cars.

Hey Nate,
Have there been any updates on the Eisenmann connecting pipes for these exhausts yet?

First set is coming in from Germany next week. Once test fit is complete on our sedan (BMW does not offer the E90 M3 in Germany) Eisenmann will start producing them.
