I have CB one here in england for sale,with the required fittings,I also have a bugpack one,but its in a container somewhere in the ocean on its way still
For a simple road car set up I prefer the CB version due to the compact size and ease of fitting and plumbing,we have a few customers who have bought them and given positive feed back on them,also with the bugpack version seemed a little loose on the tolerances,we actually had them hard anodised to tighten them up.
I also have a 3 stage pauter for sale,but its not very practical for a road car as it sticks out the rear valance a little
[well alot actually
]
cheers richie
