The one by the footpeg offers a some support to the exhaust system. he other one is the heat shield + headto muffler joint cover and is pretty much aesthetic.

You can take it off, but you are probably gonna burn your shoe.  Also, you will need a spacer or washer under the acorn nuts when you remove the heat shield, to be able to tighten down the foot rest assembly.

ok...i'll just heat wrap up to it then....would the header wrap stop t from burning my foot?

i might leave the one on the peg but the lower "muffler cover" that goes over the joint is being stubborn, the little bolt and clamp are rusted....may have to ditch it!!!!

i can't wait for someone to say "y would u do that to your nice bike?" haahaha
