Well not really a mod but I'll start with side windows tinted to match. Then I will be getting a tune, cold air intake, and a cat back. Hoping to do it all in one shot so it could be a year or so before the performance stuff begins. I'm slow moving now since I bought it out of state I'm awaiting my tags and will need to get it inspected here in PA. I bought this at the higher end of my budget so I'm just worrying about learning it, doing some research, and enjoying it, and of course paying for it lol.
