Exhaust Header 4 cylinder L16 L18 L20B 510 620

New header for L-series 4-cylinder engines, L16-L18 and L20B.  Mild stainless primaries and collector.  1 7/8" collector.  Stock replacement header.   Square exhaust ports.

We recommend the Remflex gasket for this header as it is not uncommon for the header flange to not be completely flat.  The Remflex gasket is a thicker gasket that allows for imperfections in fitment.
