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.

Trade a f.body true dual setup for the gmmg ?

no he just bought a magnaflow to quiet the car down some so he doesnt want or need that .
