On x5 it seems that only one– left side muffler is working as i see. . 2015 BMW X5 35i Msport with MPPK & MPE Exhaust– AMAZING SOUND!
I saw a couple of acura and lexus suvs and the exhaust was coming out of both sides. I also saw another x5 on the way to work and his left one .
I have found after 100 miles that only one exhaust is working. The one on the right (UK car) is working which can be seen (soot) and felt (hot air) .
I started it up and I was standing behind the car and I noticed that only the right side of the exhaust was working, meaning that nothing was .
