Ben,
If you're going to use clamps...have you looked into stainless steel instead of chrome?
-Mike V.
I haven't -- I'm figuring the chrome ones will last until I tear the bike apart for a full rebuild, at which point I'll likely do brand new headpipes and all SS hardware...
Hell, for now I might just do the hose clamp thing. I'm also considering painting my crossover with high-temp silver or black POR-15/20 paint. I have both colors handy and am finally thinking that the crossover isn't getting as pretty as the headpipes. If I do that, hose clamps are kind of a no-brainer as I'd already be deviating from the all chrome stock look.
