Matte black ceramic coated. Enhance the long and low profile of the stretched saddlebags found on a blacked-out S model Milwaukee Eight bagger. The patent pending LS275 baffle design gives the Backslash 450 slip-ons a deep rumble; the large spin formed 4.5" diameter mufflers fill out the exhaust cutouts to sit flush and in line with rear angle of the bags for that streamlined custom look that fits the bike so well. After installation take a cold one; give the result a long hard look and you''ll just feel the universe come into balance. Tech tip: Pre-2021 USA mufflers on a 2021-up EU Touring? The FuelPak FP4 (part number 942227) allows you to disable the 2nd. downstream O2 sensor; without triggering trouble codes. This will enable you to use US or pre-2021 EU exhausts/mufflers that are not equipped with a downstream O2 sensor connection.
