I posted this back in April on the yuppieracing.net forum but haven't posted it here. I figured since this E90post you guys might have spotted it around. I'm not sure if Charles (username on yr.net: Makots) is on here or not.
The exhaust setup in the video I believe is Eisenmann race exhaust with fabspeed X-pipes. This car showed with us at HIN as part of the yuppieracing.net team, it won best BMW unlimited.
