If your gonna get an exhaust, go full, with an aftermarket air filter and then do your efi modifications. Maybe just maybe some engine mods but its prolly not worth it on a ute.Has anyone tried the DynoJet Power Commander and/or exhaust mod on a Rincon. My buddy is out running me just a bit on a Yamaha 660 and I need a boost. The PCIII is the one I was considering. Any other perf. mods out there with success?
