Well i got 4-1 rite now on the car, nothings wrong with them. Only issue i have is clearnce at times. I was thinking about swapint it out for 4-2-1.....good idea or should i stick with 4-1? I know GSR is all about top end and 4-2-1 are for mid range (reason i got 4-1 in starting).

The better question would be what brand. Also what application you do more. If you drag race or street race more often than anything else a 4-1 is going to be your best bet. If you like to autox or do mountain runs then a 4-2-1 would give you a little more of a bump where you need it more. Now back to what brand. If I were building a drag/street car I would rather have a Sparks or SMSP 4-2-1 header than a DC sports JDM 4-1 header. On that same note I would rather have a Hytech or RMF 4-1. I am getting ready to put my fourth header on my car and from experience I can tell you that when you are going all motor or bolt on or spray spending the money to get a really good header is well worth it in the end. Buying a DC Sport "street legal" header is a complete waste of time and money.

^^ KINDA, but I disagree. If you are simply fully bolted this header rocks. Once you mess with INTERNALS or "go big" (N/A) it becomes a waste.

You misunderstand, it's not that there is anything inherantly wrong with the DC sports Street Legal Carb exempt header, but there is no sense in buying it at all on a DOHC Honda.
J even without internals or big NA work a good quality, MSPi, SMSP, RMF, SPARKS, HYTECH header will outgain any DC header, even the JDM 4-1 with 2.5 collector hands down. That is something that you can not argue at all. On a built NA motor, even a small build like I had with just good cams, I, H, E, IM and tuning the above mentioned headers then make even more power. My point being, if you plan to ever go above just simple bolt ons don't make the mistake I did and think well I'll just spend 200-250 on this DC now and then "IF" I need to later I'll get a better header. Get a better header now and it'll be the smartest thing you ever do on an NA Honda build. IMO a good header is the best start you can make on a Honda period. There is a reason why the JDM DC 4-1 header is 300+ and the cheapest of those mentioned as "good/high end" are 600+. That is the simple fact that they make more power and are better constructed.

Like I said, don't get me wrong, DC Sports makes a decent cheap header. Construction wise they are strong, the flanges are good and thick. But they just do not make the power. I for one just do not like to mod for the sake of modding. I just bought a cheap header because I didn't know the difference at first. My first header was a DC knockoff of the Carb header. The second was a DC sport Carb exempt 4-1. The third header was a DC sports JDM 4-1 with 2.5 collector. The third is the best header that DC makes for the Honda. However, you do need at least a full round of bolt ons to support the flow that it makes. It still will not stack up to any of the headers I mentioned previously. If Vteckidd sees this thread he can post up his header test he did with an RMF, Sparks, Hytech production header, and DC Sports JDM 4-1 2.5 collector, and a stock ITR header. The JDM 4-1 only made 2-3 more whp than the ITR and made less torque because of the 4-1 design.

I know quality comes first, but rite now i only have basic bolts on...nothing big. Most likely even if i plan to do something serious to the motor, it won't be NA.....Supercharger is the only route i am gonna go. For now i was just asking if i had the opportunity to swap my 4-1's out.....should i do it? Oh btw i really don't that much of mtn runs or Autox runs so i guess sticking with 4-1 for now will be a good idea, but when i do get enough $$$....i'll upgrade to better headers.

i still dont liek DC . i had a few sets also in my cars and all would end up leaking from different welds . and that less then a year in each header life .
