Hello... I have a Bassani Catted X-Pipe off my 2000 Cobra. The original part number is 4699-3. The down tubes are welded to the cats. This will only fit mid-lenght headers as they are now. New downtubes can be purchased separately from Bassani. If you just need the X-pipe as a replacement or have a car with mid length headers, this is the deal for you. This is the stainless steel version. Excellent shape. Can't use on my Bullitt as I am leaving the stock manifolds. $175 for stainless X-pipe only or $250 for the whole X-pipe and cats. Again, you can use the X-pipe by itself with your custom exhaust or have a complete stainless catted setup for your mid-length header Stang. Shipping to continental US only. Local Pickup in Indianapolis available too. Expect shipping to be $30-50.. Send zipcode for shipping cost. Email for pics.
