PROFLOW GM LS Cast Exhaust Manifold Raw LS1/LS2


Product Description

PROFLOW GM LS Cast Exhaust Manifold Raw LS1/LS2


  • Proflow cast iron exhaust manifolds have been designed to hug close to the engine block so they fit into a wide variety of replacement and engine-swap applications
  • Their contoured design aims the exhaust directly at the exit port for improved flow
  • Being cast iron means they will provide years of leak-free performance with less under hood noise than traditional headers
  • Plus, their shorty design means you can route exhaust tubing close to your frame/floor pan for maximum ground clearance
