Surprised at that, they cover my Akro, Hi Flo's and spacers, @ £90 extra! New docs that came through names the mods, strange that they said they wouldn't cover yours!?!
A few years ago I was with Direct Line, they refused point blank to insure the Borla I had on my RX8
companys are now starting to realise that people that modifiy there cars take more care of them usually. I imagine if i had owned a corsa vxr and wanted to put a big exhaust on it they would probably ream my rectum but because of the Z status and usual ownership type (until recently) it is a pretty respectable car so dont bum that much more onto it.
