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).

SuperTrapp Stouts are compatible with our True Duals
SuperTrapp Stouts do not fit the 2010 Road Glide or 2010 Street Glide which are single-exhaust bikes.
Note: Sound test data on '10 - '13 model specific slip-ons was achieved using the OEM CAT equipped headpipe. Use of these mufflers on headpipe with the CAT removed or True Duals will result in substantially louder results.
Optional cores are available for certain models at an additional cost.
