Is the dyno done with RON 99? Mine is remapped on RON 98, good 205/17 tires and bilstein B14. Deleted the sound actuator and added sound dampening in de boot. No optical mods. Philips sells LED H4 that are TüV approved in germany for the UP. The only mod I would like is lowering seat position and a sports seat.
Question, if you find your road+ noisy and say the full res is the one you would pick rather. Then why do this mod at all? Is there a performance gain? Or only the look of the big end tip?
I really liked the Road + exhaust it was just a little too noisy when cruising down the motorway. I would recommend the resonated version as it will still be a improvement over the original with not so much drone compared with the Road +. I doubt there would be much difference in performance and yeah the big tail pipe does look pretty cool too. It really depends what your looking for from an exhaust. hope this answers your question.
