Which side is/are your tailpipe/s located?

[XTO]

typically the tailpipe would be located at the opposite side of where your fuel filler cap would be located.

So if you fuel filler is on the left side, the tail pipe will be on the right side.

normally yes, but how about those having dual pipes like the santa fe’s, camry 3.5’s and others? do the manufacturer follow a certain design standards to come up with this? and those trying to be "in" by converting theirs into dual sided. i've seen some gen 2 CRVs and accords with those exhaust mods.
