Toggle Switch.

The handlebar-mounted toggle switch allows on-the-fly transitions between loud and quiet modes.

The small chrome actuator motor is mounted to the frame.

The small chrome Actuator Motor, mounted to the right front frame tube, receives the signal from the handlebar switch and opens/shuts the Diverter Valves via heavy duty cables.

The valves open and close with the switch, reducing sound when needed.

When the Diverter Valves are closed, the exhaust gases are routed through the Peacemakers' patent pending AeroBaffle, reducing the exhaust sound volume to a lower level.
When the Diverter Valves are opened, the exhaust gases flow through the straight pipe down the center of the muffler, resulting in increased exhaust sound volume and greater engine performance.

National Cycle® Peacemakers®

State and city lawmakers are getting an earful from the public about motorcycle noise pollution. Peacemakers® Slip-On Exhausts allow you to get the sound you want—at the flip of a switch—yet still exercise social responsibility when needed. It's the solution you've been waiting for!

Imagine being able to start up your Harley® for an early morning ride without angering your neighbors.

Imagine enjoying a deep, powerful exhaust note without cringing whenever you pass a police officer or school zone.

The new Peacemakers® Exhausts make those dreams a reality.

The sound changes when the actuator opens and closes the internal baffles.  Loud or quiet exhaust at  the flip of a switch!

Universal exhaust pipe builder kit from Bitwell, Inc.  Build your own pipes!
Builder's Universal Exhaust Pipe Kit - Biltwell Inc.

This Builder Exhaust Kit is exactly what its name implies: a selection of pre-fabbed tubing, header flanges and exhaust tips that puts the art of custom exhaust building in the hands of backyard fabricators. Each Builder Exhaust Kit includes the following:

Two 16-inch-long (350mm) straight sections
Two 3.5-inch radius (90mm) U-bends with straights
Two 5-inch radius 134mm) U-bends with straights
Two Evolution flanges
Two Shovelhead flanges
Two Ironhead flanges
Two STD flanges
Two fishtail tips

In other words, everything you need to build a set of pipes for one bike, with enough scraps left over to start on two more. If you’re clever—and assuming your stable of projects includes the right combination of Harley motors—you could build three sets of pipes for less than 300 dollars. All it would take is a visit to the local muffler shop for a couple more feet of 1-3/4-inch steel tubing.

WHAT’S MISSING: This kit doesn’t include mounting tabs. You can fabricate these out of flat stock, or buy some at any good industrial hardware store. Snap rings and exhaust flange collars for Evo are not included. You can pick these up at any swap meet or local shop.

SURFACE FINISH: All raw tube sections are pre-polished to make chroming after joint finishing easier.

NOTES: THER ARE NO LOOSE FLANGES OR TIPS. FLANGES ARE ACTUALLY WELDED TO THE U-SHAPED PIPES.

Part #: CC632735... $168.83 including shipping!*
