I'm trying to put this shorty muffler (emgo) says it should fit 1 3/4 and 1 1/2 pipes...i've got 1 3/4 inch pipes on the bike, but the muffler is way too loose. clamping won't seal, but I don't understand how it would clamp anyway, since it's not slotted, there's nothing to clamp. I could drill and secure them with a screw, but it'd still be too loose.
My question is, can I just make some shims? Or am I missing something? And if I can make them, what material, aluminum? Can I use a fucking beer can?
These are the mufflers:
These are the pipes, not that it makes a difference:
