Dominator Mufflers for Triumph Bonneville & Thruxton


Back again after long embargo and formally sold under the name “Predators”:

Slip-on performance mufflers for the Triumph Bonneville (wire spoke & mag wheel models) and Thruxton.  Constructed of 304 stainless steel and offered in your choice of mirror-finish polished, or high temp black ceramic coated.

Two (2) sound levels are offered:  “Touring” for a more civilized exhaust note, especially over long distances, and “Sport” for a more aggressive exhaust note.  Power output between versions are within 1 to 2 HP of each other and significantly more than stock.

These mufflers are manufactured in the US by Cone Engineering.  Regrettably, these mufflers are not available for sale or use on California licensed vehicles.


Cone Engineering designed and manufactured the original Dominator muffler.  It is one of the most sought after mufflers for Triumph Modern Classics.

A few years ago, the new Touring Series was created for those wanting a little less roar.  The original muffler was renamed the Sport Series.  Choose the original Sport with a straight-through 1.75 louver core wrapped in stainless steel wool.  Or go for the newer Touring, featuring the same size louver core, but featuring a unique internal deflector cone that lowers the sound level.

Both versions fit on the stock headers and use the stock clamps.  The muffler mounting bracket attaches in the stock rear foot peg location, either with pegs or with eliminator mounts.  The Bonneville/T100 fits with or without the stock center stand.  The Thruxton and Mag Wheel Bonneville CANNOT use a center stand.  All mufflers come in your choice of bright mirror-finish polished 304 stainless steel or flat black high temp. ceramic coated.

Not available for shipping to AK, CA or HI. Remaining lower 47 states only.
