Congrats!!!
The dealer shouldn't give you any problems with an aftermarket exhaust and the Dinan tune. Not sure about the suspension, but I don't think I've heard of any issues with that. Unless you value how your car will sound over maximum power potential, I would definitely recommend getting the Dinan tune. It's almost the same amount of money as an exhaust and the tune gives you a 25% increase in power.
