FRPP SGT axle back mufflers for sale. These are the SGT version for the GT500, not the 5GT version. They have 1700 miles on them. I do not race the car nor drive it in rain or snow, so they are in excellent condition. I will ship in the original Ford Racing box for $300 (plus any insurance at your option) to US addresses. I will ship after receipt of funds via paypal or money order or certified check. Thanks.
