Supertrapp int. disc Slip-ons FXD99-up

SuperTrapp staggered dual slip-on mufflers are very cost effective versus a full system and give your bike a significant increase in Horsepower. These chrome plated, 3 1/2" (8.9 cm) outer diameter, mufflers in a tapered design with SuperTrapp's 3" Internal Disc design are tunable for sound and performance. Very easy to fit as these mufflers slip straight on the stock headers of all 1999-2017 Dyna Twin Cam, except FXDF Fab Bob, 2010-2017 FXDWG Dyna Wide Glide and 2012-2017 FLD Switchback.
