Thunderbike Performance Mufflers
100% stainless steel replacement mufflers for the Triumph Trophy. Noticeable horsepower and torque improvements throughout the rev range with no requirement for carburation change.
Designed and developed to give a very nice exhaust note that compliments, rather than detracts from the ride experience of the Triumph Trophy.
Simple to fit.
We are unsure if these mufflers will fit the earlier models (pre 99) without further modification.
Exhausts are made to order and the lead time to manufacture is 3-4 weeks plus shipping.
