Ok. Its got a custom cold air intake with AEM pod, a Cat-back (part 2 1/4" and part 2 1/2") exhaust with a 7.5" Cannon (5" tip), and a heavy duty clutch. Many more mods but that's all for engine mods. Not quite sure if there is any other mods that i don't know about, as all engine mods except for the cannon were done when I purchased the car.
