ive been looking at headers and although id like to get one of the nice ones like the amuse or other comparable ones, i just dont have the cash. but the dc sports header is really affordable as well as being CARB approved. i was wondering if anyone had it and what their impressions of it were. from their description of it they say it increase hp and tourqe at all rpms but i know that many times when installing headers you tend to lose torque. is this the case or are dc sports claims about the performance gains fairly accurate?

 

The DC header has been shown to actually LOSE power. There have been dynos posted a long time ago. Maybe search will find them?
Even the one time seller of DC headers admitted that they were not a good header. This was after he got out of the business, I think.

 

Garbage!

 

The new Import Tuner has it in the power pages and it shows a few hp gains. I don't personaly have the header but it is worth reading the article.

 

On an S2000?

 

Yes I don't remember what year model I want to say 02 or 03. They also did an AEM intake and I don't remember what brand exhaust.

 

i had i liked it...
i didnt lose power i gained a lil mid range tq.
peak didnt change.
for the money its good

 

it's easy to fudge dyno numbers
the real question is how reliable was that dyno test?

 

sorry mike I did not see your post before I posted
no offense intended

 

I recently installed the DC Sport header in my S and noticed a small gain (5-7 hp) on the dyno in mid rpm torque and hp. I did not gain anything on the top end. I have no temp readings for the intake or coolant, and the runs were not done at the same time, so take it for what its worth.
