Kerker options

Available in chrome or black, Kerker Stout 4” slip-ons are massive, non disc-based 4 inchers that use a more traditional core than the SuperTrapp Stouts. The streamlined, tapered end cap with recessed fasteners comes pre-installed. Described as providing a “bold, strong power curve from mid-range on up with a +9.6 (+17%) hp and +9 (+12%) torque gain over stock, at 5 dB over stock, they are louder than SuperTrapp Stouts, providing a classic, deep, throaty rumble.”

Also available for ’10 – ’16 FLH models in a kit which includes SuperTrapp’s unfiltered 2-into-1-into-2 head pipe that “substantially outflows the stock unit,” it utilizes the stock heat shields for a cleaner and sleeker appearance and it has O2 ports. They are also compatible with chrome or black SuperTrapp True Duals or the SuperTrapp Crossover conversion adapter kit.    
With optional chrome or black end caps available and sold separately as replacements, or to mix and match for a customized look, they fit Baggers, Tri-Glides and Street Glide trikes.

Also seen here, Kerker K Series slip-ons for ’16 Night Rods have a 2.5” baffle, are 13 lbs. lighter than stock and are said to provide Night Rods with “that deep, bold, signature Kerker sound.” Made with brushed aluminum impact-extruded canisters, the core and packing are rebuildable.
