You will notice im not in your country, im in Australia. Its still illegal here, but thats the last thing they would worry about here. It be teh single, external with screamer pipe, pod filter, fixed bucket seat, too loud, too low etc etc. I think in the UK to have a car rego you must pass all these first? Well in Australia, its much easier, rego can be done online
Handling is fine for the street, but at the end of the day, I drive the car very normal on the street, as getting pulled over for speeding can then result in the defects mentioned above, but drive normally the policia will be fine. I have my track 17" rims for when I go to the track and really let loose.
