I just compared my Tourer's heat guard with an Interstate set I
have... I don't see a difference... They have the same part
numbers (I looked up 97 and 2000)...
Sometimes people mount triple tips so that only two mounting
screws line up. Does that make triple tips hit the heat guard?
I'm pretty sure Honda's plan

was to mount them the way
all three screws line up... they sure don't hit the heat-shields
that way...

I haven't looked at my Interstate set of pipes lately, I think I remember
that you'd have to cut the piggies on Interstate pipes to get triple tips to
fit (or maybe mount them in the two-screw-only orientation?) ...
