hey can anyone tell me the difference between the nova 41019 and the new 41032 manifolds.to me the look the same in pictures.reason i ask is i have a modified reds r5r and it makes its most power with a 9886/41032 and all i have is the 9886/41019 at the moment.what if any gains can i expect from the 41032 manifold.or should i just stick to the 41019 manifold.thanks for your help
