SOLD!!!
I have both an OEM exhaust and Agency power catback exhaust off of my '09 370Z.
The Agency Power exhaust has around 5,000 miles on it and was only on the car for 5-6 months before I switched it out with a Fast Intentions exhaust. Has no dings, and is I excellent shape. $550+ shipping. Also willing to drive to Atlanta or a surrounding area to meet to sell it.
The factory exhaust has a little less than 30,0000 mile on it, and was taken off to put the Agency Power exhaust on. $150+ shipping. Also willing to meet in Atlanta or surrounding areas as well.
