yes, before we set up the exhuast set, need to understand our's engine cam profile first .... so, when people voice out their opinion, of coz have point of view.
like Taiwanese set up exhuast system at GTI , 2 stage pipng was using to cover from low rpm until high rpm , this was included strong torque at low rpm and can push out max power when high rpm .
F1 won't have any exhuast system , just 5 in 1 x2 header then direct push out .. why ?? because they want good respond.. when gas pump out fast , engine will suck in fresh air fast . :lol:
