The HKS canisters are different. Those are resonator chambers (notice how they are big on one end like a resonator and arent just straight piping capped off at the end) with perferated holes in them and packing, probably a more expensive version tuned to do the same thing in a smaller space. This article is mainly for the FI guys who have drone and want to fix it but that is the idea.
The Saclam exhaust however has side branch resonators, its the side pipes people were calling backpressure tubes. Check out the layout, they just put theirs further up the exhaust system. It's probably why their exhaust sounds like a race car up top and doesn't kill your eardrums cruising around inside the cabin. The pipes in the middle that parallel the main exhaust pipes are side branch resonators, the length clearly tuned by Saclam to get the note they wanted.
