Check the clearance on the seat, and the front fittings, seriously, looks great, I know 3 other people who had the same experience as me. The leather touches down on the cast subframe and one guy had the leather wear through in under two weeks use. Mine did not fit properly at the front either, they use a V shaped fork, to fit into a square section seat peg.
I had the unit garage low exhaust, the baffle was shonky, so I moved that on and went back to standard, also found out they are made by Arrow, so can be bought from them for £150 less than unit garage (The Low Exhaust I'm talking about)
Exhaust bracket is great though, but the rest of my unit garage stuff has very much been a mixed bag quality wise.
Looked great, but you can see some of the clearance problems here, it does not look that big in the picture but it was just over 20mm from the seat to the tank, I could have made new brackets but should not have to on a £400 seat.
Good luck though, the hight level exhaust is a thing of beauty, post up some pictures..
