Redthunder S/O Polished FLH/T17-20 E4

Slip-On mufflers install quick and easy on the stock exhaust headers. Tailored by Italian craftsmen from stainless steel for the muffler body and billet aluminum for the end caps. The E-approval makes them street legal all over the European community. Muffler bodies are high luster mirror polished or tough Cerakote black finished. These mufflers fit only on Touring models produced for the European market (VIN starting with 5HD). Slip-On mufflers for 2021 to present models feature, like the OEM mufflers, the bungs for the rear O2 sensors.
