They have both 100 and 200 mate.
It'd be more free-flowing (slightly) than a 200, but it's debatable that you'd feel any difference between 100 and 200. Should still do the job with the emissions and flat spot though, the 200 is great for that. Better than standard with the flat spot and from memory the emissions was virtually identical as standard too... I'll have to dig the MOT's out, quite intrigued to know myself now.
Think there's a bit of a price difference from memory, £75-80 or so.
