Luckily for you no engine mods exist
But you can tighten up the suspension, tint, wheels (save some unsprung weight).You could add a full or axleback exhaust. Rallisport v2's haven't been tested yet and if so no idea how that woudl trow off the emissions, which would result in a problem, which the dealer would deny b/c you added hardware that causes the PZEV hard/software combination to not be effective.
There are tuning options but they may result in warranty claim denials. You bought a car that never built up an aftermarket following or owner pool that desires to "take it the next level".
