add £27.68 to that as it ruined a brand new set off plugs on mine as the car ran that lean after fitting,needs the map tweaking instantly in my opinion,i paid £150 for the Y pipe,delivered,£150 to fit (5 hours labour),and £150 to tweak my map at RS Tuning,once you've bought the original map its £100 an hour for any future mods to be mapped in,so all in all it cost me £450 plus the plugs,bangs load every single time you change gear though:thumbsup:
