Tubi told me today that the Propella and Propella Race tips are discontinued. The F430 will only be available in the Classic Tip (like the 360) or the Competition Tips which is similar to what they use on the Maserati Quattroporte. If anyone is in the market there is a F430 coupe and spider muffler available with the tips following in about two weeks. This muffler is a direct replacement for the factory one and it allows you to use the factory tips. The GTC system is more of a race system and it requires its own tip design. This system will be available sometime in late October. The least expensive way to go is to purchase the coupe or spider muffler and then buy our Exotica Motorsports exhaust tips. These slip over the factory tips and set screws on. You can see them in depth here. http://www.exoticaferrari.com/installation_page.htm Purchase this muffler and we will pay the 2-day shipping for you. Our tips will be ready to send out next week.
