hahhaha... 4-1 goes from 4 pipes into 1... 4-2-1 goes from 4 pipes to 2 pipes then 1 pipe

no the graphs from the link lol

jdm 4 1 work well and give a nice beasty thump sound

[TheSaint]

well im left wondering if 4-1 run really well and give a good sound than whats the point in 4-2-1? im keen to ge a toda header but im not gona fork out that much money unless i know wat im doing lol

excuse the noobness but wen ppl say 4-2-1 are better for midrange power does that mean mid revs or mid speed? same for high end? and is it really that different to 4-1?

[TODA AU]

TODA 4~2~1 offer stronger mid range without sacrifice in top end.
Mid range & tope end refer to revs.
The other significant advantage of the TODA header is power at part throttle positions.
That is there is more power / response avaiable through transient throttle positions.
This is why when TODA headers are fitted, people notice the difference straight away.

SPOON race headers man its funcky shit

[TheSaint]

man toda - full of great information

now i just have to process it all and decide whats right for me...

wich is better for street use? i have a dc2 vti-r and i would think it would need more mid range to push up to vtec quicker... but once in vtec u stay in hi rev range for longer... so which way do u go??

Im trying to deside between TODA and 5zigen atm..
half the price of toda but still makes good numbers

Yeh, Im thinking of using either Toda or 5Zigen header as well.... Tough call

5zigen are not all that great, but ok for the price i guess.


The 5Zigen header showed a substantial gain in the 3000-4700 range, due mostly to the header's ability to smooth out the power curve before VTEC kicked in. Gains in this region were as large as 14hp to the wheel. Since horsepower ratings are extrapolated from torque, a corresponding increase in low to midrange torque was expected and seen, with a large majority of that increase right around the 10 lb/ft range. Because the entire powerband was shifted upwards and made more linear, peak horsepower topped out at 147.7hp - a median gain of 9.6hp.

From what i have read around on u.s forums toda make similar power to the hytech headers tested.

[locote]

TODA twice the price.
on a stock motor maybe a couple of Hp difference, worked more but 5zigen plus use left over for cams make way more power...
might have to sleep on it..
