Give Kingsley Wright a ring at Roton Engine Developments Ltd on 01244 536555- you will find that they have a web site if you search under Roton- I suspect that price is in the region of £400 for cat back system but price would depend on your requirement- they are very professional and will give you exactly what you. As a matter of interest thay have produced a rotary valve head which sounds VERY interesting- should produce exceptional power and smoothness. |
