Thunderbike Triumph Rocket III Performance Muffler System

This is our performance muffler system for the Triumph Rocket 3, it retains the original heat shields for that factory quality finish and look but eliminates the collector/catalyst box.

These are available as a 3-3 system similar to the originals but tucked in instead of the splayed out look of the factory originals and also as a 3-2 system with only the 2 mufflers on the right side.

Gain nearly 20bhp, more torque than you will know what to do with, lose 5.5kg's (12lbs) and make it sound like it should do.

Please note: We offer a 6 month warranty on all chromed products from the date of purchase, the same as Genuine Triumph.
While chrome should last longer than that in some environments/condition, there are others (eg, coastal situations, or areas where salts are applied to the road, or even storage in a moist environment, like a steel container or unlined steel garage) where chrome can fail very quickly indeed. Chrome has a very porous finish and should always be waxed to prolong its life.

These Guys are awsome by Adrian 25/09/18
Ive had a set of Thunder Bike Exhaust on my Rocket for a couple of years now and Im still smiling - They sound great look the part and last extremely well which is testament to the quality of the product.
Fitting was no issue and shipping to the UK was quick.

My thanks to Kevin and everyone at Thunder Bike - All the very best
