Many thanks to all those on this forum who were able to help resolve this problem. Armed with the information given, the people in the workshop facility in Cooma were able to fabricate suitable tailpipes from four 2 ½ inch tubes. These were bent up to about 5-6°, the ends were blanked off about two inches in and holes cut into the underneath. The chrome tips we initially had installed were then relocated to the ends of the new pipes. A couple of photographs illustrate the modification.
The end results look quite respectable but I haven’t been able to really test the new arrangement to see if it works because it was raining on the trip home. Kevin, it’s funny that you should say that about Bristols rarely being seen in Cooma. There were more visitors to the service facility than usual on that day, apparently the 410’s presence caused a bit of interest.
It’s interesting to note that the solution to the issue of these cars creating areas of low pressure around the rear can be quite complex.
This exercise also illustrates how valuable a forum such as this can be to operators of these cars – thanks Kevin!
