I’m back at Mountune to have the axle-back exhaust system installed on my Focus RS, but in the mean time it would have been rude not to take the MR265 Fiesta ST out for a little drive on some of the tightest countryside roads I could find.

Overhauling the standard car, Mountune’s top package takes power up 65hp, torque up 80Nm and brings the 0-60 down from 6.9s in the standard car to 5.7s. With all of that through the front wheels and a chassis that is set up like a go-kart, it makes for a hilarious amount of fun to drive.

More to follow with my new Focus RS exhaust in due course!
