    FlowTech REAL-SEAL header and collector gaskets are a revolutionary break-through in exhaust sealing technology! Constructed of multiple layers of "Dead Soft" aluminum for a reliable and reusable seal, the individual layers allow the gasket to conform to imperfections in the cylinder head and the header. Out of the box are designed to work with the FlowTech's Afterburner and Shorty Smog headers but they are easily trimmed for applications that require custom port matching. !

    Features:
  • Reusable design will not burn or blow out
  • Perfect for applications that require port matching
  • Multi-Layer aluminum conforms to create a leak-proof seal
  • Water and weather resistant
