Toda has longer primaries than the Comptech and I THINK it is slightly smaller in diameter so it create less resistance for the exhaust flow and increase peak torque on the higher RPM band but drops quite a fair bit off after it's peak. The length determines how the torque curve is set and the diameter determines the peak torque relative to the RPM.
The bottomline to making power from the exhaust are that the exhaust has to quickly remove the combustion as quickly as possible and the velocity must be high too.

ooOoOOo interesting.. lol i just picked up my injen CAI 2day and im hoping 2 get extractors by the end of this yr.. and im not sure which headers 2 get yet lol..
extractors and headers are the same thing or did that statement follow on.
do you have alot of money to blow or do you just want bang for buck?
TODA/MAXIMWORK/J-Racing (bloody expensive) ------> DCSports/Comptech/Topspeed/Xforce (cheap as chips)
to fit a JDM header you will have to fit a jdm cat as well. with mine, the Random Tech cat is cut and welded to fit. Hanger of the header also needs to be rewelded as JDM header's hanger position is a bit more backward then OEM if you know what i mean. JDM headers will have more gain over CL9 ones coz they are all longer ( the 2-1 connection of CL7 is behind that of CL9). Ah sorry about my FOB engrish.
