I bought one from Ducatipipemod.com and had it fitted last week along with a PCIII usb. I have to say it's fu**ing loud!... Much louder than a standard Termi!
To be honest his welding job was pretty awful and I made him refund me some of the money to have this sorted out.
Also the finish of the Tips isn't that good as well. If you do manage to get some made up let me know as I really want another set welded onto the exhaust to finish it off nicely.
The bike performs great though and is pushing out just under 106BHP at the back wheel which isn't too shabby for a standard '03 749... Plus you can hear me coming from about three miles away!
