Bought a 2014 road king twin cam 103, wanting to get rid of the catalytic converter and install some headers. Getting a bit confused on the difference if any between the 2+2 or 2+1+2 headers. Not sure which is the best way to go. Been around motorcycles my entire life but this is my first Harley. Hoping I can draw upon the Harley gurus on the forum to educate me a bit to figure out what’s the best way to go.
