Cone Engineering Dominator Sport Mufflers Air Cooled Thruxton / Bonneville


SKU: N/A Category:



Cone Engineering designed and manufactured the original Dominator mufflers that became the most popular muffleer for the Triumph modern Classic. And now they are available DIRECT FROM THE MANUFACTURER!

Original “Sport” baffle with a straight-through 1.75” louver core wrapped in stainless steel wool. Also available in “Touring” baffle, featuring the same size louver core, but featuring a unique internal deflector cone that lowers the sound level.

Utilize 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 bright polished 304 stainless steel.
