SuperTrapp Sout Slip-Ons are brewed to perfection. These non disc-based, massive 4" Slip-Ons make bold statement. The '10-'16 aps feature a newly developed, tapered core. The streamlined, internal tapered end cap w/ recessed fasteners comes pre-installed.

SuperTrapp Sout Slip-Ons provide a heavy, broad spread power curve right from idle w/a 9,3 hp ( 16%) power gain measured on a stock 2010 FLH. Torque gain is 14%.

At 95,6 dB@2000 rpm, or 2,4 dB over stock, these are SAE-J2825 sound compliant.

SuperTrapp Stouts offer beautifully crafted, 4 "slip-ons with a pleasant sound and unsurpassed performance gain.

Sound test data was achieved using OEM CAT-equipped headpipe. Use of these mufflers with TrueDuals ST167-72580 will result in substantially louder results.
