Yeah, I imagine it’s not too difficult to swap out the stock one.

The exhaust on that blue bolt is similar to mine, except mine is shorter and fits on directly on the stock O2 sensor coupling spread to fit.
GS500 naked's are awesome, in fact there is a huge bunch of people that love the angular 89-00 over the newer 01-02 with the favorite being the 89, with clipon's the frame upper rail without a gusset, 6 position gear indicator bobbin, aluminum shock linkage etc etc.
That white one with racing stripe like a CB750/1100F from the early 80's is my favorite, I keep a body set around just so I can slap it onto any GS I like. I also have a set in black.
