dont put exhaust or headers or any of that engine crap on your car. Its brand new and your gona void the warranty. dont drop it 3 inches later; its gona ride like hell and not be a luxury car at all anymore. wheels tint, and some good springs thatll give u a 1.5-1.75 inch drop. drive it for awhile before u put exhaust on it; if u do go catback only
