This is nothing to do with me, but following my problems with my exhaust cable and actuator (now sorted), I was half looking at other options for the longer term. I came across this Termignoni exhaust on ebay selling for what looks like a good price. The part code they quote is wrong (F4342X0), I rang up the seller and asked them to find the part code on the box which is BU05102TO which would appear to be an earlier version of the current BU05094TO racing silencer for the 2008-11 XB9 and XB12 bikes. At 94dB it's too loud for me, but someone might like a bargain on this
