Exhaust most definitely! I had new exhaust within 2 days of bringing her home and it took that long bc I brought her home on a Friday at 9pm. First thing Monday she was in the shop getting flowmasters. These cars need a good rumble, way too quiet stock. And a CAI helped with throttle and sound as well. First 2 mods that should be done IMO
