Interesting. Do you have any idea what the purpose of the resonators is? I wonder if I should try and get hold of some? I had a look in the Range Rover workshop manual and can't find any reference to them.
thats a big question, lots of sources of info, but itstillruns gives a good overview.
i'm guessing it runs just fine as it is and I can't imagine any possible way it could affect oil consumption
Very interesting, thanks for the link. I want a resonator now, I don't suppose anybody has a spare one lying around do they? That probably explains why my car is louder than it should be.
