I pulled an exaust from a donor EA81 today. It has one more chamber in it than mine.

I'm guessing the first chamber at the header end is a resonator
Second chamber must be a pre muffler
Third chamber main muffler.

Does this sound about right?

Also can some one tell me what these parts do and what is inside them and which bits I can do without?

The exhaust pipe had a fair bit of rusty water in it. Does this mean its toast?

Looks like what was on my old '81 wagon. The front one is just a collector, I think it is completely hollow. It helps make sure both cylinder banks see the same exhaust back pressure fluctuations. The second one is a straight through resonator muffler -- it quietens things down a bit, and doesn't really restrict flow. You could remove either/both of them, and it wont do much/any harm, but it wont gain you anything either.....

I wouldn't worry about the water, if there is no holes then the worst it will have done is corrode the baffle tube in the resonator, reducing it's noise reduction performance but not leading to any adverse flow restrictions...
