Bagger Nation / Kerker 4” Stout Mufflers from SuperTrapp The latest from the minds at SuperTrapp! The new massive 4” Stout mufflers are brewed to perfection. The look completely bitchen, sound badass and offer unsurpassed performance gains! These larger, chromed bodies are brewed to perfection. Available for ’95 – ‘11 Baggers and 2011 and earlier model Tri Glides. They offer a newly developed high flow core and produce massive horsepower over stock mufflers. The streamlined, Internal Tapered, Billet Aluminum End Cap with recessed fasteners comes pre-installed and is a sign of the true craftsmanship that went into the design of these totally new pipes. The newly shaped inlets flow better into the OEM head pipe as well. Of course Bagger Nation version of the Kerker/ SuperTrapp® Stouts’ tapered core is unique and only available through the Bagger Nation catalog and web site. Our pipes are way louder than stock and all packing has been removed for maximum flow and a totally unique thunderous sound. SuperTrapp Stout Slip-Ons provide a heavy, broad spread power curve right from idle w/ a 9.3 (16%) hp and 10.5 (14%) torque gain over stock (measured on a stock 2010 FLH). So if you truly have a hankering to be a speed freak the choice is obvious…Go Stout or go home!
