SE Series have been used by one of the world’s largest OEM’s for years. They’re the champion of numerous magazine shootouts with a 10 – 12-percent horsepower gain. SE’s are the king of bottom-mid range torque with a steady, tough, low rumble and are only 3dB louder than stock.

Kerker Slip-Ons have a proven 12 – 13-percent horsepower gains with great mid-high range power. Kerker Slip-Ons are 8dB louder than stock with a profound, deep, throaty rumble. Adding a Mikuni Core provides peak performance and ultimate flow. SE Series and Kerker Slip-Ons are non-tunable. They’re compatible with 17 end caps, including the brand new, Yaffe-designed Holy Moly end caps, to allow riders the ultimate in personalization.

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

Megaphone Series are the 4″ diameter disc-based exhaust that SuperTrapp claims as their “signature” muffler. Megaphone Series provide an 8 – 10-percent horsepower gain. Includes a rebuildable core and discs.

FatShots feature a 3.5″ diameter and the fully chrome plated muffler bodies flare out to a 4″, slash cut end with a straight through 2″ diameter, pillow-pack wrapped performance core that is capped off with the legendary SuperTrapp 4″ discs and polished trim ring.

By adjusting the number of discs, FatShots Slip-Ons have the ability to be the quietest performance muffler out there with a richer stock level sound, but enhanced performance. It performs better than stock in a sound compliant configuration.

If you want to kick it up a notch, installing the recommended 12 discs in conjunction with its straight through 2″ diameter performance core sets the stage for maximum power. In this configuration, FatShots Slip-Ons provide a 15-percent hp gain and a 12-percent torque gain over stock, proving, your exhaust does not have to be loud to make power.

FatShots Slip-Ons come complete with twenty-four 4″ discs and all of the necessary hardware and mounting instructions, so you can get back on the road in no time.

Mean Mothers Slip-Ons offer the same loud and throaty, drag pipe sound as the original Mean Mothers, but are 2 ¾” chrome-plated heatshields with a stainless steel 2 ¼ expansion chamber, with Black Ceramic Coated Billet End Caps. They also include a removable louvered core.

All of SuperTrapp’s tunable Slip-Ons 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. Non-tunable SuperTrapp and Kerker exhausts provide horsepower, torque and exhaust tone enhancements without having to add or remove any discs.

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.

The Road Legends Baffled, FLH Phantom Pipe is a curvy 2:1 pipe, based off of the original which is a drag pipe, but this one is baffled and therefore neighborhood-friendly. Rather than a slash cut, it has a decorative billet end cap with engraved domino dots. The FLH Phantom Pipe comes with 4-piece stylized chrome heatshields. It extends past the rear foot peg and ensures a cool ride, even for the passenger.
