You also have a delay as the pressurized intake charge has to transfer through some fairly restrictive piping back to the front of the vehicle. Why not put that same turbo under the hood and not worry about rocks, trees, mud and excessive turbo lag. If you put it up front it's easier to put in an intercooler too, netting more power. It also makes for an easier engineered and installed system, helping keep costs down.

Long tubes def better, but the purpose of headers is to increase scavenging of exhaust gasses allowing a better and more complete fill of intake when limited to atmospheric pressure and ram effect for cylinder filling. Turbo overcomes this by introducing pressurized charge - more air and fuel and more power as result.

(my driver side manifold has a hairline crack so a short style header is in the plans anyways)
