Arrow Emma's Obsession With Flatulence (Eisenmann Sport)

Back a while ago, I had a chance to compare the OEM exhausts with that of an Eisenmann Sport set. Suffice it to say... I was impressed:



So after a bit of thought (and a lot of rummaging of couches for spare change)... these German engineered beauties found their way home.





Comparison between the two (both weighed about the same at ~22.5lbs on the home scale):


Halfway done:


Done!


After the install, I had an opportunity to test it out for an entire day. I looked at the entire rev range as well as sound levels at different speeds (cruising, soft & hard acceleration). Relative to its form and function, I can conclude (again) that these are the perfect mufflers for anyone who wants a deeper, louder exhaust note but not over the top.



The sound is just intoxicating, yet mature enough not to disturb the neighbours. It really is an amicable setup... loud when you want it to be and civilized while cruising (at ~60-70mph, they are actually quieter than stock). The sweet spot seems to be at ~2500-3000rpm when the sound just shuts out. Below that and you get a nice deep rumble. Above that and the sound is mean yet purposeful. Damn, I'm chuffed!



And the best thing of all... NO RASP! You get a couple of burbles/pops, but not too much so as to make it annoying.

Trust me the video didn't do the Eisenmanns justice. Both my car and Rick Hunter's M's were completely cold. And I mean COLD. We just turned on the ignitions and started shooting the videos right away. The Eisenmanns sound even better after the car's been warmed up for 5~10 minutes. The revving could've been a little more aggressive as well.

I recently heard their race exhaust on the newer M5 and was blown away... I am sure it sounds great on our car too.

Updated.



Since I was on the streets, I didn't go for any hard acceleration. But you should get a sense of what it sounds like inside the vehicle.

Yeah, it definitely doesn't sound bad...I kinda like the stock exhaust note, just hate how it looks. The eisenmann's are much much better looking.
