Valve 1600/1750 Race Lite Weight Special 8x37mm 45 degree Exhaust, Each


According to our research these special shaped exhaust valves with 8mm stems make better power than both stock  37mm or oversize 38 mm valve by reducing over-scavenging. 

  • The special back side shape improves flow.
  • At 74g, this valve is 19g lighter than 9x38mm race valve or stock.  This is worth power since the exhause seat pressure can be reduced.
  • The 1mm smaller stem allows better flow.

NOTE: We can special order any valve size you decide is best for your engine.
