M2 Motorsport Header Stainless Steel Subaru Impreza

Unequal Length Stainless Steel Header. M2 exhaust manifolds not only offer significant performance gains across a range of areas but are also manufactured to the highest of standards. Unlike many other performance manifolds our headers are produced with a three bolt hole" flange between the manifold and the up pipe to ensure a long lasting leak free seal. Manufactured with slip joints in the centre of the manifold also allows for expansion under temperature changes so as not to place unwanted stress on welds and removing the need for un-reliable flexi joints."
