Well this past weekend I had a few friends over to help install the Remus Exhaust kit that I got for the X3. It was pretty simple to install, and the most time consuming parts were just cutting the rear valence, and getting all the tips lined up right. The tips I chose for it was the Akrapovic tips, and since I got them off ebay, I have no idea if they are legit but they look really good. But managed to get a quick video and some pics. The phone mic doesnt really capture the sound that well but gives you an idea.
