Now available for the new water-cooled Triumph Modern Classic.  It features the Dominator Sport straight-through louver core that Cone Engineering created for the original Dominator mufflers.  Because we utilize the OEM exhaust headers and catalytic converter, you get a nice deep tone in a cone/reverse cone style, but smaller and lighter than the OEM muffler.  Since stock cats remain in place, no re-tuning should be required.

As with the earlier generation Modern Classics, this new era Dominator mounts to the stock headers.  The muffler mounting bracket attaches in the stock rear foot peg location, as with past Dominator’s but installs BEHIND the passenger foot peg mount using a provided replacement spacer.

On the new model bikes the kickstand stop is in the header and the frame so there is no additional stop needed.

All mufflers are manufactured from 18ga 304 stainless steel outer bodies, balancing lighter weight and strength.  The finish of the muffler is matched to the stock header finish.  A black ceramic finish is a special order option on all versions.
