There are a few cosmetic changes but the big differences are the ride, the diff (I believe it came in the 2010's as well) and the instrumentation. All the rest is the same. The ride is the biggie. I have an 08 and love it but I am also looking for a reasonable 2011. As for fake exhaust tips, lots of high end cars do the same so that shouldnt be an issue.
Good luck.
