Richard, I too enjoy the sound of induction never more so than when messing around balancing the twin Webers on my Elans many years ago, though for a real sense of induction roar while in the drivers seat, it must be hard to beat a mini with the Weber protruding into the passenger compartment through the hole in the bulkhead where the speedometer used to live.... Backfires, and wearing loose items of clothing were best avoided for sure...
Running an older car sans electronic and emission gubbins can have its advantages, but even my car did not escape completely as it is fitted with an auto choke mechanism where I would much prefer a simple choke cable. but then best not to get too cocky for older cars like mine may be amongst the first to suffer some sort of legislative decree if Climate change really takes hold in time. and even at this time cars without cats are seemingly banned from some cities outside the UK..? NOT that I tended to frequent large cities by choice while touring... I suspect I may be one of the very few who just drove past Rome while touring Italy in my old Morgan..!!!
