I have a 4" straight pipe and it doesn't drone at all. I have heard the 5" has a lot more drone than the 4". Most guys with 5" end up putting a muffler/resonator on to tame the drone down a tad.

I notice some drone with my AFE 4" and may put a muffler on.

Have you tried going to any local diesel shops? There is more brands out there that sell resonators and I'm in Canada too and had no problem getting one. I bought a twister brand resonator from a local diesel shop in Alberta.
