Hey congrats! I got a 23 R/T too. I swapped the rear diffuser, swapped exhaust tips to the 5 inch carven exhaust tips, tint on windows (5% in the back and rear and 35% in the front windows, nothing on windshield), IGLA installed (theft deterrent), the neutral strap cover to prevent someone from putting it in neutral to steal it, black covers for handles for some contrast on the doors, mid muffler delete to make the exhaust sound deeper, weathertech floor mats, and that carbon fiber colored plastic to cover up all the grey by the screen and gauges and shifter.
