British Customs 2-1 Low GP Carbon Exhaust for Triumph Bonneville & T100 / Thruxton 900
Born from the heat of Thruxton Cup Racing, the 2-1 Low GP Carbon Exhaust isn’t just another full system—it’s a direct response to what real riders demanded trackside. Developed with input from Thruxton cup racers pushing their Thruxton 900 to the edge, this system is all about functional minimalism and pure riding feedback. The left-side exit exposes the chain and sprocket, a nod to British racing tradition and a move that instantly cleans up the bike’s profile.
Every detail is purpose-built for riders who want more than just looks. The 304 stainless CNC header bungs, California-made 2-1 merge collector, and spring-secured midpipe and tail section are all race-inspired, designed to flex under load and handle real-world abuse. The GP Carbon canister is our lightest yet, helping you drop over 14 pounds compared to stock—transforming the bike’s agility and making every input count.
Throttle response is immediate, with a deep, authentic British twin soundtrack that finally does your Triumph justice. The system’s 1.5" head pipes and free-flowing merge collector unlock torque and midrange punch, letting you ride harder and with more control. Installation is straightforward for a full system, and the brushed finish integrates seamlessly with the modern classic lines.
If you’re serious about making your Bonneville or Thruxton 900 feel as sharp as it looks, this is the exhaust that delivers.
