i want an hmf slip on for my honda rubicon 500 05' model and i heard you have to jet it to have the exhaust is it true or not? thanks

yes

if not it will run like crap
it wont need as much of a jetting change as it would with a full system but it still needs bumping up

most OEM's run them a little lean stock for emmisions sake anyway
