Description
If you’re running a Harley and want real power gains without sacrificing ride quality, the S&S Cycle 4.5″ Mufflers deliver measurable horsepower and torque improvements while producing the aggressive exhaust note your bike deserves. The dual-construction design—combining a stainless steel baffle with RaceTEX cartridge packing—cuts through the noise without losing performance, and the removable dB reducer lets you dial in exactly the sound level you need for the road or track. Built in the USA with styled aluminum endcaps, these mufflers are engineered for serious riders who demand both aesthetics and real results.
