Cobra USAPowrFlo 4.5-inch Mufflers

PowrFlo 4.5-inch Mufflers. Fitment is manufacturer-stated (URL/breadcrumb model code + year range, plus own-page confirmation), not inferred. Own page states "QUALIFIED MANUFACTURER DECLARED U.S. 50-STATE LEGAL EMISSIONS REPLACEMENT PART ON ALL 2017-2020 HARLEY-DAVIDSON FL TOURING MODELS" - bounded to 2017-2020 per that explicit claim, narrower than the site's general "17-23" catalog grouping label for this model family.
