Hello, does anybody know where I could purchase a set of 4" discs for a SuperTrapp muffler? Would you be able to buy these in Geelong or Melbourne? Who would be the quicket by post in Australia? As I opend up small holes, where long screws went back into muffler because holes were tight and damaging the threads, as I had taken these out a few times to modify end cap. I have tightend screws up as hard as I can, but now when you rev the motorbike the discs sound like they're viberating, but the only thing Ive done different is opened up the bolt holes a fraction to make it easier to dismantal. BUT SOMETHING IS STILL NOT RIGHT!  I'm the learning the hard way.

Cheers, FatboyGooch.
