Here's a video of my recently installed Eisenmann exhaust, same day as this post. Purchased from Vivid Racing, it's the Race version I believe, it was annotated on my order, but it doesn't say as much on the manufacture plates on the muffler. Anyways, my car is a 2011 N51, only other mod I have is the AFE Stage 2Si w/oiled filter which is also uploaded on my channel. It was DIY up until I got to the muffler and I couldn't attach the resonator pipe to the muffler so I ended up paying $40 to finish it, so I rolled around with a muffler delete for a while, quite interesting but not refined. The interior noise is not like OEM, but it is still refined until you WOT and it sounds amazing! Exterior noise is great when you have the windows rolled down, no drone at all. Throttle response is much improved and I am quite curious about what power gains resulted from it, butt dyno seems to indicate it's much better. Next on the list is to do Active Autowerke headers and then finalize with their stage 3 tune.
