All SME turbo manifolds feature merge collectors that are CNC machined for perfect flow and quality. They are professionally tig welded and have machined flange surfaces for a perfect leak free seal. Each manifold design has been dyno tested to ensure you get the best product possible. Working with some of the best tuners in the country and using customer feedback, SME are at the top of the game. Their products meet customer demands and they let the products do the talking on the race track with some of the countries fastest cars using SME manifolds and products.
SME have even flow bench tested manifolds with great results showing that we get a vacuum in the opposing cylinders which scavenge the gas out of the combustion chamber of the non firing cylinder. Other big name brands tested have not had vacuum in the opposing cylinders. This a big advantage for SME and their customers.
