I guess mainly with stock exhaust and some software.
With the race-kit, it is not euro 4 anymore.
I know a guy here in Belgium that ordered one and will use it as a daily-commuter
why not..
Wait a minute! Even with wet clutch, with the race akrapovic it won't be road legal anymore. It's about emissions and noise! However clutch affects more the noise than emissions (to the best of my knowledge).
So the question is how the f did they pull it off with standard exhaust? The standard one was already boarder legal line in terms of sound. What is it 92 db? 95db? for the V4 with standard exhaust? The dry clutch would easily bump that by 5 db.
