Mr Hyde 44 Report post Posted December 27, 2016 I'm not sure if this has been shared before (if it has apoligies) but I did this to my car the other day reffered to as the golf tee mod. By unpluging the actuator in the trunk it apparently opens the flap in the left exhaust. Took 2 seconds and it sounds great at lower rpm along with the alpina gearbox flash on the downshift. I didn't get any errors pop up on the dash. Here's the link if you want to try it. http://www.e90post.com/forums/showthread.php?t=80661 Sound clip of startup with acutuator unplugged. I didn't have a sound clip of the standard setup but most owners would know what theirs sounds like on startup. IMG_1326.MOV 1 Quote Share this post Link to post Share on other sites
