just fetched the car back from having the new system built by a local guy who builds zorsts for race bikes the header lenght was calculated exactly
for the cam timing giving optimum flow.He's at bilsthorpe in Notts and does the full system by hand "engine specific" for around £700
anyone interested send u2u for his details
