does that directly mean non modded AT should start from 50mm and look for 4-1?kanazai2001 said:goose...
for 2.0L non turbo AT car exhaust setup...
4-1 header (back pressure)
50mm (160 - 220hp) or 60mm (for 180 - 240hp) piping wrap with heat insulator
no cat (ori cat purpose already subsituded by 4-1 header)
single resonator (center bullet)
S flow muffler (back end back pressure)
:secret: to improve ur low end torque...
route ur air filter to throttle route longer... SXE10 is designed for high end torque... thus the route is really short... :regular_smile:
by the way... im not sifu... im still a tou-dai... pai seh pai seh... above mentioned is what i have been told by the exhaust sifu n from the internet... so... follow only lor... coz no accurate way to calculate optimal exhaust pipe diameter... all based on experiences...
i m running without cat and 4-2-1 head..kanazai2001 said:book store...
if u want to get away the cat... yes... u need 4-1 header to get back ur low end torque for AT car... :_:
check all other toy AT cars with FE head (optimized for low end torque)... all r using 4-1 headers... :regular_smile:
oohh... ok thanks kanazai for the info.:embaressed_smile:kanazai2001 said:goose...
