Car will be road legal, from what I have been told as long as there is no modifcation to the chassis sections I will be ok. Haven't had it confirmed yet though... Regardless, I'm sure a big exhaust tucked neatly above the chassis with tunnel section will get me less 'attention' than if it is hanging too low and obvious....
Have had a look at Niscorts link already, will have a look at the prefab and other link.
Thanks guys.
