I've got Stage 2 and cat free exhaust. At Zandvoort a few weeks ago I got it up to 110mph on the start/finish straight, 2 up, in race leathers. My car was very stable at that speed. It was a dry track though.....

It was also very reliable and immense fun, as I thrashed it round and round the circuit over that weekend. I even became quite impressed with the Blockleys....at long last!
