New to this site with some questions
Just picked up a 2013 550xi about three weeks ago and I truly am amazed by this car. I have a couple of questions. First off, I would like a bit more rumble from the exhaust. Sometimes I feel I'm in a prius lol. Has anyone tried a muffler delete or something similar? This is a lease and I do not want to purchase a cat back. Second, I have also noticed a throttle lag from stop. I read somewhere in the forum about an update that corrects this. How can I find out if my car needs this update? Sorry for the long post and looking forward to some feedback. Thanks!!!
