09/04/2007 Experiment temporarily suspended due to suspected air leak at inaccessible joint.
After a couple of months with the new pipe work fitted I have come to the conclusion that the system gives slightly better fuel consumption but only on a longer distance. The reason is very simple, the exhaust does not get hot enough when travelling locally as I do but for anyone who uses a vehicle on long distance driving I think that the fuel saved would be worth it.
I'll continue to use the system to see what happens over a period of about 6 months as the weather improves and the ambient temperature increases
