SuperTrapp and Kerker Stout 4″ Slip-Ons larger, chromed bodies are brewed to perfection. These non-tunable, massive 4″ Slip-Ons allow riders to make a bold statement with their newly developed core. The streamlined, internal tapered, billet aluminum end cap with recessed fasteners comes pre-installed. The newly shaped inlets flow better into the OEM head pipe as well as SuperTrapp True Dual Head Pipes.

The SuperTrapp Stouts’ tapered core is minimally louder than stock. 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). At 95.6 dB @ 2,000 rpm, or 2.4dB over stock, SuperTrapp Stouts are SAE-J2825 sound compliant.

Kerker Stout 4″ Slip-Ons utilize a more traditional core which targets a higher spread of power providing more mid range RPM up through redline. They provide a bold, strong power curve from mid range on up with a 9.6 (17%) hp and 9 (12%) torque gain over stock (measured on a 2010 FLH). Louder than the SuperTrapp version, Kerker Stouts are 97dB (per SAE-J2825) or 5dB over stock with that classic Kerker, deep, heavy rumble.

Tri Glide riders will be thrilled to know that SuperTrapp’s FatShots Slip-Ons will also fit their ride. These 3.5″ diameter, 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 than 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 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% hp gain and a 12% torque gain over stock, proving, your exhaust does not have to be loud to make power (as tested on a stock 2010 FLH).

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% 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% horsepower gains (as tested on a stock 2010 FLH) 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 compatible with 17 end caps.

Internal Disc Series provide a 10 – 15% horsepower gain (as tested on a stock 2010 FLH) while allowing your Trike to maintain a beautiful, conventional, OE style-looking, chrome muffler. Heat shields, chrome end caps and discs are included. Fishtail, Tapered and Turndown are compatible end cap options.

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

Mean Mothers Slip-Ons offer the same loud and throaty, drag pipe sound as the original Mean Mothers, but are 2 ¾” chrome-plated heat shields 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, disc-based exhausts come complete with discs, necessary hardware and mounting instructions. Adding discs allow the rider to increase horsepower, exhaust tone and flow. Subtracting discs allow the rider to reduce sound and increase low-end torque.
