I'm looking to get an stainless/mild steel manifold for my glanza but unsure which one to get as my hot pipe runs over the manifold? I have seen a couple of glanzas which also are running the hot pipe over the manifold and have managed to fit a zisco ram horn style manifold, which really is the style I am looking for! Can anybody confirm for me if there is any modification needed to fit it or are they designed to go with that hot pipe set up? Any help will be appreciated! Thank Sam
