I have the TT bash plate on my XTX which i take off road occationally and have a big trip to Italy planned in a couple months where it will explore the mountains in North Italy. Its fitted with a scorpion 2 into 1 and just fits. The front bracket is very close to the 2 into 1 manifold but it did fit. To make sure i used a simple file to make a 3mm grove in the bracket to give a little more clearance as the motor moves just to be sure. Its a hefty bash plate as well, cover the fuel pump.
Check out this thread i started to see pics of the exhaust and plate on page 2:
XT660X touring trip to Italy. Advice please.
