DC Sport 4-2-1 header

[Boost]

Anyone here using DC Sport header or Toda 4-2-1 header?
How is the clearance of the DC sport 4-2-1 header? And how does it compare to the Toda header??

I posted this in the stickied bang for bucks topic

http://bob123e.tripod.com/thegreatheadertest/

its a comparison of the major headers... it doesnt have the 4-2-1 dc sports design though the jdm dc sports 4-1 design seems to have been tested... seeings 4-1 is designed for max output and it is 3hp less than toda 4-2-1 it is probably fair to say dc sports 4-2-1 is leven less again - as 4-2-1 is designed for low to mid end... this is using logic though... i think one this would be agreed upon and that is that toda spend more time on r & d

the american section of clubrsx has a a few commentarys about dc sports headers... mixed opinions in all

Thanks for the link mate!

Toda header looks pretty promising then...

If you have the budget and want a header that will work with just about any
B-Series engine setup you will not get a better off the shelf header than Toda Header I have used them on a few cars and am VERY IMPRESSED with the power they make and where they make it from, low RPM till peak RPM.:thumbsup:

I agree with what dynodave just said. Although i've been running HKS 4-1, which let me say run a dream for me, I've been considering to swap to TODA 4-2-1 for ages. My friends run it on their type Rs and its a beaut.

nps =)

If tuners are giving it the toda a nod... ud be wise to save up for a toda... its better to spend a bit more and ensure contentment... that spend a little less and kick urself later =)

Thanks for the feedback guys.... yeh i think it is better off to pay the extra $$$ as well... get it right the first time...

hmm hands up all who want todas.... <= *puts hands up

we'll see if we can source 'em from toda au at a discount price or something.... :)

[DynoDave]

So everyone still says that 4-1 makes more top end power and 4-2-1 makes bottom end mid range I must be missing something still please click on the link http://www.titanmotorsports.com/timohohesh.html .In my eyes the Toda Header is still the best value Top Shelf Header that you can get.

The only problem is a Hytech Header costs US$1300...

[kenshin]

todas are just as pricey... but with todas you know you'll net gains

although its been proven the difference is slight between known brands

oh right.. guess i havnt been doing enough reading then... :D
US$1300?.. hhahaha.. bit costly.. but you get wat u pay for most of the time.. so i guess if u can afford to go the extra mile.. then....

I think if you pm Toda_au he might look after you better than US$1300. Toda are very nice but those SMSP and Hytech extractors are hand made works of art. They are probably more suited to upgraded cams and higher CR though.

Regards Dyno DaveI have read like articles, which challenge the notion that 4-1 make more top end and that 4-2-1 make more mid range... I was merely going of the dc sports website where they, themselves, clearly state that they design their 4-2-1 for mid range and their 4-1 for top end... For anyone who is interested the link is...

http://www.dcsports.com/product_headers.asp

If they say this is what they design their headers to do... it is fair to assume that this is how they have designed their headers...

As i understand and as is acknowledged on that page, tuning to a large extend negates the difference between 4-1 and 4-2-1 - provided its a good header...

My point being EVERYONE doesnt still say that 4-1 makes more top end power and 4-2-1 makes bottom end mid range.

[BF]

I also acknowledge the problem of comparing 4-2-1 and 4-1 of different brands...

Just because dc sports designs it 4-1 to make more top end power, does not mean it will produce more power than the toda 4-2-1...

Ive also never seen tests within branded headers.... ie... mugen 4-2-1 vs mugen 4-1... because if they are the same I would ask why it is mugen makes both?

Id be interested to see the results

companies makes different design ie, 4-2-1 or 4-1 to suit your goals. in a race, your hardly spend time below 5000rpm, so obviously you need to put a header that help you extract the most power where your rev range is located.

not all header is the same, looks the same but you need to see the welding, the connection of the pipe, the bend, and what material it is used are some of the key things to look at. of course there are other things as well...

. do you know that some metal expand more than the other? when metal expand, the volume of exhaust flow is affected. some after a while, leaked in the welding zone.

with headers, you get what you pay for . some headers are not cheap becos of the man hours and the quality that is needed to ensure that they dont fail during the clinical period like in a pro race. can u imagine that there is exhaust leak in a marathon race of 20 laps for example....

i am not in this saying cheap headers = not good headers, but one need to be very careful as you might end up paying more in the long run. and yes some do rust as well.

same quesiton here: 4-1 morepwer at top end? and 4-2-1 more power at mid range?

yes but today's hybrid 4-2-1 give the best of both worlds
