so i worked with a really cool guy a few jobs ago who grew up in tokyo in the 80's... basically japan passed crazy strict laws about modifying vehicles, basically if they caught your car with anything not-stock they would take it and crush it.
the yakuza were so powerful that the like super hardass gangsters would build these cars to flaunt the fact that they owned the cops in the neighborhood and the cops wouldn't fuck with them.
so when you see a bright pink car with 8 giant chrome exhausts, the guy who built that was telling people 'dont' fuck with me because i own the cops'
i've never seen any other english language site explain that angle of the whole thing but it makes it infinitely more badass and interesting.
i've got a double maxi boszu i've been working on for a few years but its pretty low on my list of projects, i've got a stock dual exhaust port cylinder and a host of zany one of a kind parts i've been stashing for years.
