Point taken... That notification has me spending too much time here today as well!

During this event, my friend preeth made similiar numbers to how his car is now (stock) muffler, when he had this dyno his car had full exhaust (rogue engineering) so the muffler itself did nothing but sound.

The bimmerworld race exhaust on the other hand claims 10-15 hp. but people have been getting 20-25 and even more.

Dyno Meet Weekend of Jan 25-27, 2008 - Page 5 - BMW M3 Forum.com (E30 M3 | E36 M3 | E46 M3 | E92 M3)

So with real numbers like these, then I can say the exhaust did something extra besides sound.

Unfortunately I don't see any opportunity to get mine on a Dyno in the near future.

ALSO make sure you are buying eisenman, not eisen haus. The imitation chinese brand that no one can even tell anymore, not even vendors!

It's an Eisenmann Race exhaust; I'm 100% positive. I'll do my best to get some pictures and a video in the next week or so. In the mean time, maybe someone else with Eisenmann X5 4.4i experience can jump in here!
