RoadieSL had a question, we shouldn't try to talk him out of it. He just wanted to know what brands are out there. Not why he should(n't) get them.
I can understand the desire to go to them. I may do it too as my HKs are cracked (as you all know

) This is what I like about them:
-from the rear it looks more proportioned/balanced and not so right heavy
-from the left it adds more chrome
-From the right it shows more of the rear wheel (nice if you are changing wheels out or adding chrome swing arm covers) (though that rear brake is huge, but you can change that out too

)
-Can get gi-normous saddlebags like Tsukayu Super Jumbos without mounting them so high, you can carry children in those

not that I've ever tried
-fin exhausts have the old school look to them IMHO
They look especially cool if you lower the bike and put on some fat fenders, a cool paint job, & new wheels. Now I'm talking him into something
Different strokes for different folks. The perfect exhaust is the one you like. I've heard nothing bad about the Freedoms that nopork sells.
