Changing the rear muffler will only change the sound of the drone. I found that out the hard way on the Thunderbird i had and a friend's Civic. You'll need to add a resonator somewhere towards the middle. Not sure if the exhaust on an Mk1 is similar routing to the mk2 (I'm guessing it is as an Mk6 has a similar routing to a mk2) then you can add a small resonator in front of the axle.

Very true. It is the wave that passes up and down the pipe that causes the drone. It's mainly caused by having a straight pipe for such a long distance. You need something to break up the straight line.

I'll take it to an exhaust shop locally and see what they have to say about it. Thanks heaps guys. I might put some pics up if I can get under it so you know what is under there already.

By Local do you mean the Blue Mountains?
A good friend of mine had a family friend in Penrith who owned an exhaust shop and did excellent work. I don't know if he's still around but he was just near the Westbus on Mulgoa road. Cobra exhausts or something like that.
