Small Block E-top Headers

CMI Small Block E-top Headers

    Compatible with GM Small Block LT Siamese port engines.

    A direct replacement for heavy, highly restrictive cast iron exhaust manifolds

    Design constraints with cast iron manifolds create internal air resistance, making it difficult for exhaust gas to flow freely as it exits the cylinder head. This lack of exhaust flow hinders peak performance.

  • Performance gains in both horsepower and mid-range torque
  • Increased Fuel Efficiency
  • Lighter weight 316L stainless steel
  • Available in satin or polished finish
  • Patented “Cool Collar” design provides a short hot section at the flange, which helps minimize the possibility of water ingestion in to the engine.
