Tomei EJ255-EJ257 Unequal-Length Header for Single Scroll EZ30/EZ36 Internals 9Sensing Range 0High Efficiency 4 1 Type We introduced the high efficiency 4 1 as against the STD 4 2 1. The exhaust efficency of the standard exhaust manifold is not perfect. But Tomei 4 1 type exhaust manifold has high efficency. You could see the change of dramatically driving feeling. Not Equal Length Design The complete equal length is good for the exhaust intervention but reduce the turbine performance and increase the exhaust resistance. Contrary to that, the
