Hello Members. Thanks to all those who replied to my under windscreen panel.The car I purchased is a Gordon Russell special i.e. uprated to S spec.Twin dellortos,ast road cam. four branch and 4 outlet exhaust. Can this conversion be reversed or tamed down to make car more civalised.regardsTOG
Sounds like the exhaust might be the cause of your problem.
I would be interested in swapping my single output stainless steel exhaust for your four output version. I do not intend to do much cruising on dual carriageways or motorways in the Western Isles so a bit of extra noise would not be a problem
