I bought mine from Italian sellers via Ebay. At the time I bought the pipe, sestamarcia-racing-parts was the cheapest at 750€. Upmap T800 with suitable cable was 290€ at genialmotor.
I haven't a clue if they ship to your location or the costs involved. But I've bought most of my parts and accessories via ebay from international sellers. Including also original Ducati parts like my DQS. Lot of stuff available in central Europe and USA.
