In the coming weeks we will have a new replacement header for all 1.6l MK1 models that not only looks fast but aso will make your car faster. We are currently testing the manifolds and will keep you posted on the results. The manifold will be made from stainless steel with stainless heat shield, fittings and gaskets. The first test manifolds we made have an exhaust pyramid in the area where the 4 pipes are joining, so we have a nice flow.
