Closeout Exhaust

Save 25% on British Customs’ retiring Triumph exhausts—while supplies last. We're officially closing out the GP Slip, Predator Carbon, and 3.5 Predator Carbon exhaust systems to make way for our all-new Builder Series. This is your last chance to own these iconic exhausts before they're retired permanently. Once they're gone, they're gone for good.

We're streamlining our product lineup to improve stock availability, reduce backorders, and speed up shipping times. This closeout event offers a unique opportunity to grab proven performance parts trusted by Triumph riders worldwide, at a significant discount.

The GP Slip exhaust is compact, aggressive, and race-inspired, featuring a lightweight stainless steel body with a clean, bolt-on fit. The Predator Carbon blends a carbon fiber body with a stainless core for a stealthy look and a refined, fierce sound. Meanwhile, the 3.5 Predator Carbon delivers a bold, deep tone with noticeable performance gains, making it a powerhouse upgrade for Triumph Modern Classics.

There’s no better time to act. These exhausts are now available at an exclusive 25% off, but only while inventory lasts. As a rider favorite, they’ve earned their place in British Customs history — and this is the final opportunity to make one your own. Once these models are sold out, they will not return.
