Toyota HD-FTE Split Run Exhaust Manoffold

Oops, looks like you forgot the pics..........

Looked at the site and see the manifold is made to direct one half of cylinder output through a Half circle port to turbo and the other half cylinder output to the other side Half circle port immediately before entering the turbo. The only thing it would do is increase the velocity of each stream of hot gasses entering the turbo, no increase in volume though, instead of premixing with exhaust from the other end of the engine at the junction before the turbo entry. Less swirl and more direct I suppose. The question is, does the half/half design actually reduce the ease of gas exit from the cylinders at higher flows when full power gas flows is asked for? Hardly worth money unless you are experiencing less performance down low. Maybe have the valve clearances on the buckets looked at first as they have to be correct for an benefit of any mod or normal use to happen correctly. Remember, Toyota NEVER check valve clearances unless a power problem is found to be real. Not uncommon for Toyota engine to have 250K or much more and NEVER had valves checked.
