For those who aint heard of them before. They are an exhaust that is fitted and you have a knob fitted in your dash and so you can changed the sound of the zorst. so you can have it quite when you got a headach and just cruising down the motorway and feckin load when your at cruises.
Has anyone seen these and got opinions on them.
I had never heard of them untill i got the latest readline mag in the tested section. Think they sound cool but are they as good as they sound?
