What's up Mike? Welcome to the forum and congrats on your purchase! What color did you end up picking up?
As far as new exhaust, it depends on what your looking to go with (axle back, headers, full exhaust, etc.) as well as whether or not you like the stock exhaust tips (the ISS system gets rid of them while setups like Joe Z and Borla keep them). It's up to you and your preference. There is a lot of information on here for you to search/sort though. With regards to engine performance, there are a few different intake setups as well as throttle and fuel controllers out on the market with more to come in the future (hopefully).
Again, welcome and let us know if you have any other questions
