gmmg catback with the optional oval tips —$500 bucks
slp underdrive pulley with gatorback belts–$200 bucks
pulley and belts have less than 100 miles , my friend found a procharger shortly after he did the pulley and new belts.
slp lid and k&n air filter—$110 bucks
My friend is located in Hagaman Ny , Its 2 min from my house in Amsterdam to give you an idea where Hagaman is .
We are unsure of the miles on the gmmg and the slp lid and filter because they came with the car.
