Our 2-1 motorcycle full exhaust system options feature our most performance-oriented designs—tested on the track for over a decade. As the name suggests, lightweight 2-1 systems bring the left and right headers together into one merged collector pipe, increasing power in the low-to-mid-range powerband. With more lower-end torque available, you’ll feel that power in everyday riding, whether you are on the street, the highway, or off-road.

To match the significant performance upgrades, we don’t cut corners in the fabrication process. British Customs motorcycle exhaust systems are TIG welded by hand by our expert craftsmen. We use mandrel-bent pipes, precision slip-fit and spring-joined sections, and a true merge collector.

These complete exhaust systems were developed to increase performance and create unique, rich exhaust tones true to the soul of the parallel twin engine. Whether you're upgrading for aesthetics, sound, or performance, our exhaust pipe for motorcycle setups deliver unmatched quality and craftsmanship.

Our 2-2 aftermarket exhaust motorcycle options bring back some of the most classic exhaust from the Triumphs of the '60s and '70s when 2-2 pipes were the most widely used. While 2-2 Triumph Bonneville exhausts typically increase top-end performance at higher RPMs, we specially designed these pipes to boost low-end performance for a more balanced power output.
