This DBR titanium exhaust expansion chamber is designed for 2-stroke off-road motorcycles to manage exhaust gas routing and pressure wave scavenging. In 2-stroke engines, the expansion chamber geometry directly affects engine performance by utilising pressure pulses to clear spent exhaust gases and retain fresh fuel mixture within the cylinder. Constructed from titanium, this component replaces standard steel exhaust parts to reduce unsprung and overall machine weight while ensuring high thermal stability in closed-course racing environments.
