Every exhaust is designed and made in-house by our expert fabricators and welders, and we select and use only the highest-grade stainless steel for the very best construction and performance.

Our Triumph aftermarket exhausts reflect our passion for Triumph’s heritage, evoking the visual aesthetic of legendary Triumph tradition from the street to the track. We believe in the lasting quality of products made by hand by people with passion, artistic vision, and skill.

So which British Customs exhaust is best for you? In this guide, we break down what you can get out of each exhaust replacement type to help you decide.

Slip On Exhaust

Our slip-on exhausts mark where British Customs began. Our first models were introduced to the market 20 years ago, and we’ve refined our designs for optimal performance over years of testing, knowledge gathering, and customer feedback. 

Slip-ons are easy to install on any Triumph model, as they only require the removal of the stock slip-on exhaust. It’s a simple procedure, making this a great beginner mod that allows for significantly enhanced sound and performance with a unique, classic aesthetic.

Performance Tips

For riders with liquid-cooled Triumphs made in 2016 and later, performance tips are an exciting choice for those who want substantial effect on a sensible budget, with weight savings, a clean, stripped-down look, and enhanced sound.

These British Customs exhaust mods replace the stock slip-on and mid-pipe with a stylish and minimal piece that offers unrestricted, baffle-free airflow. Weight savings can be significant, shedding up to 15lbs off your bike.

Since these exhausts are hollow without a baffle, they are designed to work with the catalytic converter. We do not recommend pairing with an x-pipe without a custom tune, as it can damage your engine and affect performance. This configuration is also very loud, so be sure to check your state’s road noise ordinance before installing.

2-1 Full Systems

Our 2-1 full systems 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 collected pipe, bringing increased power to the low-to-mid-range powerband. With more lower-end torque available, you’ll feel that the 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 exhaust systems are TIG welded by hand by our expert craftsmen, and we use mandrel-bent pipes, precision slip-fit and spring-joined sections, and a true merge collector. 

These systems were developed to increase the performance and create unique and rich exhaust tones true to the soul of the parallel twin engine.
