Special "Big Flange" version of our popular "Shorty" exhaust header. A replacement for original Opel 2.0 and 2.2L cast iron manifolds (with a 75mm x 110mm wide flange), offering improved exhaust flow in a lightweight "bolt on" design. Can also be combined with other exhaust system configurations (see "part notes" for additional details). Includes 2.0L big flange gasket PN 10016, flange bolt set, set of 6. NOTE: Will not work with original head pipe flange. See 10023ss when using factory size 1.9L exhaust head pipes. Suggested header gaskets: 1.9-2.0L use Remflex OGTS PN 10012, and 2.2-2.4L use Remflex OGTS PN 6139 (Limited production).
