NEW "Shorty" style header. Fits Opel GT with 1900cc engine, and also fits Opel Manta, Ascona/1900 and Kadett models with 1900cc engine. Bolts on between your cylinder head and an original-style exhaust head pipe, which allows you to run with your original intake manifold (separate from the "heat stove" of original-style Opel exhaust manifolds). This helps engines idle and perform better when driving with today's ethanol-blend pump gas. Installs using our part #10009 flange gasket and #10011 fitment bolts which are included. Suggested parts #10012 Remflex Intake Exhaust to head, header gasket, #6048 manifold bolts to head and carburetor mounting gaskets #9004 and #9018 are also recommended). Will also fit all 2.0, 2.2 and 2.4L CIH cylinder heads, and can be adapted to fit with most aftermarket intake manifolds. Note: #6139 Remflex header gasket needed for 2.2 or 2.4 L cylinder head. Also works with all Opel fuel injection manifolds. This version is for the original small flange head pipe equipped on all CIH engines before 1976.
