I was wondering if i was going for better 1/4 mile would i go with 4-2-1 or 4-1 which one would be better for me? I was thinking lanuching really helps you on 1/4 miles, but the thing is once its up past 1st gear 2nd 3rd and maybe 4th are all in the high power band. Will the 4-1 do better than 4-2-1?
thanks
4-1 all the way, you get the most power at high rpm's out of b-series. i have dc 4-1 and they perform well. 4 2-1 you'll get power in lower rpm, which is fine if thats what you wanna go for.

with a 4-2-1 you get alot of mid range power it will be a bit deeper there to
you should only go 4-1 if you are making a ton of power, stick with the 4-2-1 and modify the collector 2.25" made a ton of difference on my teg after i modified the collector.

4-2-1 will perform best on the 1/4 against the 4-1 one the same car.
Answer the question... do you know what the difference is besides the design? I do... nothing. Unless you get a good header and exhaust setup, that DC header is a waste of money in hopes that it will create power.
Just search for previous threads on header selection... oh wait, is the search function working yet?
This thread as well as the replies that one is better than the other is (no offense) nothing but opinions.
Note to everyone especially thread starter, look a ways down for a thread on a Hytech Header-back system. Now thats something that will give real gains.

They're different due to different applications and setup. If you're running a stock cat and stock or aftermarket exhaust, i'd go with a 4-2-1. It's referred to as a torque-step header by some possibly due to the exchange of high end, high flow for some mid level grunt. I'm running the 4-1 DC's with the 2.5" collector, 2.5" Carsounds high flow cat and 2.5" after cat exhaust system. I did this to make more power in the upper rpm land (7-9K) and to prevent all possible restrictions.
I haven't ran a 4-2-1 so I honestly can't say if it's that much different or not.

my thoughts exactly. get either one, just make sure you finish the whole breathing system. don't expect to throw on one piece of the puzzle and see the whole picture.
staples - i was thinking about running a similar system as yours. i barely got my teg a couple of weeks ago. its a 97 gsr. the short ram intake is on its way so ill have that in next week. but about the headers, how high can i rev up my gsr safely? cause i know to take advantage of the 4-1 headers i have to go higher than i would with the 4-2-1. any feedback will be greatly appreciated. thanks!!

don't go past the stock redline on the a stock motor because you wouldn't want to do any costly damage to it

yeah, but would my stock engine with only an exhaust system be able to take full advantage of a 4-1 header or would i be better off just getting the 4-2-1?? this will be my dialy driver as soon as i get another job
