Which Exhaust pipe should I use?

if ya dont mind noise, HMF, and jus about everyone here is gonna agree.

i also have an 05 foreman 500 i went with hmf and yes it rocks... big diff in the power

this is definatly a hmf approved message board

IF YOU WANT LOUD BUY A TRACTOR MUFFLER

HMF All the way, just don't ride behind one in deep water, they push a lot of air which in turn throws water back on anybody riding rigth behind you.

They are loud but they have a good tone to them. Its really not that bad though.

Thank ya'll for all of the help
