Just because you don’t see stuff online doesn’t mean it’s not out there.
Madison’s old B7 had about every JHM part on it. That nogaro B7 (KoupeCrazy??) has a set of headers and nitrous, 10MPG with his B7, and that Artic White B7 Avant for sale had a set of longtubes. These are just a few I remember, however that means there’s likely tons more we are not aware of.
