2-1 Low GP Carbon Full System for Speed Twin 1200 / Thruxton 1200 / R / RS

Triumph Speed Twin 1200 & Thruxton 1200  2-1 Low GP Carbon Full System  If you ride a Triumph Speed Twin 1200 or Thruxton 1200 (R/RS), you know the stock exhaust leaves a lot on the table—muted sound, extra weight, and a look that doesn’t quite do the bike’s lines justice. The 2-1 Low GP Carbon Full System is designed for riders who demand more: more torque, more character, and a deeper connection to the road. Born from Thruxton Cup racing, this system was hammered out on the track, shaped by real feedback from riders who live for the next apex. The left-side exit isn’t just a nod to classic British race bikes—it exposes the chain and sprocket, giving your Triumph a raw, purposeful stance. Under the engine, a crossover pipe optimizes flow, while the California-built 2-1 merge collector and CNC-machined header bungs ensure a precise fit and optimal performance. The spring-secured midpipe and tail section move with the bike, eliminating rattles and letting you feel every pulse of the engine. The numbers matter: you drop nearly 29 pounds compared to stock, instantly sharpening handling and making the bike feel lighter on its feet. The sound? Deep, authentic, and unmistakably British—no more tinny or muted notes. Installation is straightforward, with integrated O2 sensor ports and a design that fits seamlessly.
