I have a Fox exhaust, Lorinser springs and spacers for the 453 moodel all with less than 1,000 miles of use. All items were purchased from Smartmadness and I have the original receipts. I would like to sell all parts together for $700 plus shipping. The Brabus rear diffuser is required to mount the exhaust which I’m not selling. It could be purchased from Smartmadness. I can send a pic of exhaust mounted on car upon request.
