We have recently installed an X-Ost Maranello Sport Silencer on a client's Ferrari F360 Spider. The customer didn't want to change the look of the car, just the sound, so we installed the Sport version (Pista being the loudest), without valves, and keeping the original tips. The install took a little over 2 hours, and the customer was extremely happy. Here is the video he made of his experience:
We carry the complete line of X-Ost Maranello and we are very competitive on pricing. If you want to update the sound of your Ferrari or Maserati, drop us a line and we will be glad to write up an estimate.
