Developed for competition use in the Thruxton Cup, the British Customs 2-into-1 Exhaust is a track ready system engineered to get you off the line and down the back straight, ahead of the pack. The 2-into-1 left-mount Exhaust system gives you unparalleled low-end grunt with a substantial increase to mid-range performance.

Designed to give your Triumph Bonneville a stock appearance looking at things head-on, that all starts to change as you circle around. The right side of your bike is completely exposed: the alternator case, sprocket cover and driveline deliver form via function while the right side header crosses over to the left via the factory crossover location to merge into a 2-1 collector.

Available in a brushed stainless. The brushed stainless system will develop a lustrous pattern over time, creating a raw performance look.

when paired with the air injection block off and air box elimination kit, I got 69.83bhp with a power commander V. doesnt hurt that it is lighter than stock and has a badass bark to it!
