Just been talking to Raask to see if I can list them. Their current UK agent is M&P in Swansea.I have only heard good things about them (so far). Busters also list Raask slip ons part number RAASOT11ST at £318/pair. I did some development work with Trident for stainless slip ons, but I have to say they were definitely NOT good on that occasion. Hope this helps.
