This BMW E92 M3 Exhaust Will Make Your Monday A Little Better

I went on the dyno with my BMW E92 M3 to do a few test/tune runs with the new APE X85 (E85) Flex Fuel Kit and although I did the runs with minimal ethanol the results were pretty good. Unfortunately getting max power wasn’t the goal of this session so I’ll be going back with a full tank of ethanol to do some performance runs, but for now you can listen to the Supersprint Race Exhaust and Macht Schnell X-Pipe setup recorded on my Tascam professional audio recorder and Rode stereo mic stitched together. Get your headphones or earbuds and watch this video.
