Does anyone know if there are catalytic converters in the HEADPIPES of my 09' Ultra???
There are some folks bragging about their collector (headpipe) showing an HP gain on the dyno. Some others are selling complete sets, depends on what you want, and what you want to spend.Thanks for the quick replies. The bike was originally purchased in FL.
So, if there are no c c in the headpipes, would there be any advantage to getting aftermarket head pipes...?
