When you choose a British Customs exhaust, you’re choosing a product designed and handcrafted by a small but passionate team in Gardena, CA. We believe in uncompromising design integrity, something that informs every step of our process.

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.



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.

Predator Carbon

The Predator Carbon is an ultralight stainless steel reverse cone with carbon fiber end cap designed to offer a premium and high performance option to Triumph riders.

Predator Pro

The original modern classic slip on, the 4" reverse cone design pays homage to the classic 1960s cafe racer style that has inspired so many Triumph riders in the customization journey.

Shorty Predator Pro

The short and stubby little brother of the Predator Pro; the Shorty Predator Pro reduces the length of the Predator body by 6" to offer a more sporty, modern look.


100% stainless steel handcrafted slip on exhaust featuring henckel cut steel pattern, exposed TIG welds for a werkes look and sound.


Thoroughly authentic Bonneville exhaust with period correct style and "sleeper" performance hidden within.


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.

Triumph Full System Exhaust

If you’re looking for a complete overhaul, our full Triumph aftermarket exhaust systems offer the most dramatic improvements in looks, sound, and performance. Our full systems redefine the bike, removing the factory system from the headers to the tailpipe — all for noticeable performance gain.

We’ve leveraged our team's decades of riding and motorcycle engineering experience to reimagine timeless designsand create faithful British Customs exhausts, borrowing the DNA of iconic race builds of eras past while integrating powerful upgrades to boost performance for everyday riding in the modern world.

2-1 Full System

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.

2-1 Low GP System

Over 10 years of design, tested vigorously on the track through the Thruxton Cup series. Handmade from scratch:mandrel bent for optimal flow, built with a true merge collector, finished with a GP pipe with tig-welded piecuts to really show the art of welding. Often imitated, never duplicated.

2-1 Low Shorty System

Over 10 years of design, tested vigorously on the track through the Thruxton Cup series. Handmade from scratch: mandrel bent for optimal flow, built with a true merge collector, finished with a Shorty Predator pipe. Often imitated, never duplicated.

2-2 Full Systems

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

2-2 Shotgun High System

The 2-2 Shotgun High Pipe System really gives a meaning to "modern classics" for us, mixing classic looks with modern technology. From mandrel bent headers, TIG welds, louver core baffles to carbon fiber heatshields, this system is a blast from the past.

2-2 Tracker Low System

Vintage flat track style pipes inspired by Gene Romero's factory TT racer build, this entire system is unique from the oval mandrel bends on the header to the two cones with exposed TIG welds, this system is essentially our work of art.

2-2 Slash Cut TT System

TT-inspired pipes, built in collaboration with Sonny Nutter based off of pipes on his vintage race bikes with low profile right exit turn out pipes. Stainless steel, louvered baffle system.

2-2 Drag System

Dirt Track inspired straight pipes. Stainless steel, louvered baffle system, lightweight.
