In the actual area, the internal structure of the genuine 2in1 part is skillful and the torque band is wide, so it is meaningless to replace the genuine 2inn1 part in the street mainly.this 2in1 exhaust manifold has the advantage of replacement only when the regular rotation range during circuit driving is high.please note that the fact that the low -speed torque is lost by replacing the exhaust manifold often is due to the combination of characteristics different from mass production and parts selection.
