Well, I'm with Carole Nash and I phoned to tell them I had fitted a Termi on the 749S. It put my insurance up by over £100 a year! They know which one it is now though, and at least I am insured. I asked about other mods, and they said they were only interested in ones that affect performance. I don't know how much performance they think I am getting, because it still gets 100bhp on the dyno WITH the termi.
