I have slip-on termis on my 748; no idea where I would be able to get decibel killers for them? They are pretty loud and I would guess that they would fail noise tests at some circuits e.g. Croft – at the moment they don't have a hole to take any baffles can anybody tell me where they got theirs from and whether or not there is any particular way of fitting them without having to drill a hole in the bottom?
Just look through selection on fleece bay and pick ones which will fit your cans. Holes will have to be drilled. I have never had a problem on noisy days running a 54mm system on my 748 thing
