The SuperTrapp and Kerker 2:1 SuperMegs both work with OEM forward and mid controls.

Both are available in chrome or black. The SuperTrapp 2:1 is tunable and provides a 15% bolt-on horsepower gain across the board. Both feature a rebuildable core and packing.

Internal Disc Series are tunable and provide a 10 – 15-percent horsepower gain. Heatshields, chrome end caps and 3″ discs are included.

The Road Legends X Pipes, another Yaffe-design, offer that over-and-under shotgun look and sound. X Pipes offer that classic, deep, loud, drag pipe tone.

The removable louvered baffles come pre-installed. Optional end caps and heatshields are available to customize the look.

Mean Mothers are serious. They offer a 33-percent weight savings and an 8% horsepower gain over stock. These are drag pipes with a Hot-Rod sounds that lets out an intense, booming roar. Three different end cap options are available. The pre-installed baffles and heatshields are also replaceable.

All Tunable SuperTrapp exhausts include discs and truly demonstrate the performance and customization that a tunable exhaust has to offer as it doesn’t lock you into any one type of sound or performance. Rather, it allows you to adjust your exhaust to your riding style.

Adding discs will increase the horsepower, exhaust tone and flow. Subtracting discs will reduce the sound and increase low-end torque.

There’s something for everyone.
