Post Eisenmann "SPORT" Exhaust

Just purchased the Eisenmann "SPORT" Exhaust, so I guess I am going to be "the canary in the coal mine" since no on else has purchased/installed or even heard this system. The OEM system is pretty loud straight from the box. In fact it is by far the most aggressive sounding OEM exhaust I have ever had on any previous M car I've owned before. My E90 M3 was 'Civic' quiet in comparison. My goal is that this system changes the tone without getting too loud. Regardless, the quality of the Eisenmann is superior to the OEM and it will tuck under the rear valence nicely. A few extra hp's maybe, but not expecting huge gains.

The Eisenmann "Sport" will increase sound levels over OEM system by ~3db's but should be 1/3 the volume of the "Race" system. I plan to do the Akrapovič downpipes next and then finally an ESS tune to round out the performance mods. The system should be here shortly after Christmas and on the car early January. I will update with pics/video and my evaluation at various loads and RPM's.

Would like to thank Josh, Gregg, Scott and Sean at VIVID Racing(in AZ for hooking me up:
Of course thanks to Ilia and Nate at IND for your help as well!

This clip was recorded with an iPhone 4s after 2k mile break-in on the exhaust.
