Hi all,
Im new here to the forum and I have a 2014 ltz 400 all stock except for a two brothers m7 slip on exhaust. What upgrades could I do to add more power without taking the engine apart? Ex. Header pipes, fuel controllers, chain and sprockets? Any suggestions?

Don't really want to go internal on the motor yet. Looking for parts for the fuel injection motor. Most of that is for the older carburated model.
