all that i know of is that they silence the exhaust a little, well thats what i hear. I acutaly want to get one becuase my hmf is crazy loud....Cops suck ;D
They shift your powerband more into the upper end. They will quiet down the low end a little, but your top end will be very loud with it on there. Basically it allows the exhaust to flow much better when you really reaf on the throttle.
THe ol PB Header. I bought one kept it for months sold it then bought it back from the same person I sold it to. haha. Funny thing is that was months ago and guess where its at...Laying around the garage just like it was before I sold it. I should have it on by summer. hahah
