Flowtech exhaust manifolds are the perfect combination of quality and value. This Rams horn exhaust manifold fits all popular hot rods with the popular small block Chevy motor.

  • Tight fit block hugger design for popular hot rod and street rods powered by the popular small block Chevy motors
  • Cast iron construction styled in the vintage Rams Horn design for maximum engine clearance and maximum strength
  • Smooth transition, 1-5/8 diameter primaries are used for increased exhaust flow increasing performance and improving throttle response
  • 3/8 thick 2-1/4 collector for maximum strength
  • Thick header flange pads for a leak-free seal and maximum strength
  • Premium aluminum header gaskets are included
  • This manifold is raw "uncoated" so it is perfect to paint match or coat to match engine or body design
