Some bloke near my work has one (Stalybridge) with open pipes on. Sounds like thunder and he can't half get it over coming off the BT roundabout! Very cool!
Interestingly enough, have a look on fleabay, theres a couple of SP1's below 3k - one seems to only have high mileage (33k), up for £2200 buy-it-now!
