Header for the Toyota EFI 22 R. If you are looking for a true "seat of the pants" power upgrade, then this header is for you. Headers allow your engine to breathe better, letting more exhaust out. Horsepower may be increased up to 20%. This header is application specific (not generic) with smooth mandrel bends, and even flame tested. Header comes with manifold gasket and collector. It is amazing at the differences you will feel.  As with all headers, check to see if this allowable in your area. This is a quality made header.
