British Customs 2-Into-1 Exhaust System for Triumph Bonneville / T100 

Developed for competition use, 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.
