Cheers Tabetha, yeah I had an Ashley system on an orion years ago and seem to recall it being way to loud and having the build quality of old baked bean tins so that was why i was hoping for someone else to still list a system for it.
I'll try calling round some of the other exhaust manufacturers and see if anyone can be of any help.
The custom SS idea is another route to go down but again I've had a few friends went to the only place in the North east of Scotland that does them and I wasn't to impressed by the final results.
Thanks for your help
