I trying to descide descideing on which header to purchase the ITR header or DC sport. the header is for a 2000 integra GSR. Which one would you get???

 

What are you looking for the most? Reliability, power gains, ground clearance, collector size, etc. It depends what you want really.

Theres a few different choices of DC headers so you might want to specify which one.

 

i'm going for performance. Whichever would give me the most gains in HP

 

In the price range, the Hytech replica being sold in the Sponsors Marketplace will outperform both.

 

wouldnt the reason the hytech type header makes power is cause it eliminates the cat?

 

You can retain a cat with that header, you just need to shorten the B-pipe. It will still outperform the others because if its design.

 

I would get the JDM ITR with the 2.5" collecter

 

if your motor is stock, just get a DC header with a 2inch collector. 2.5 is TOO much. This was proven in an issue of Honda-Tuning. They dyno tested a B18c1 motor with all the headers and a DC 4-2-1 header with 2inch collector made the most HP. The only time 2.5 inch collector would be good for is anything that is BOOSTED or High Compression 11:1 or higher.

only reason to get a DC Sports header is if you live in california.

 

^ Pretty much...

Is there such a header with a 2.25" outlet?

No, all of the CARB-approved headers have the stock 2.0" collector.

Not to offend you, but I would not rely on issues of Honda-Tuning for my information.

Thats exactly what I was thinking lol. The Hytech replica header has a 2.5" collector and is already dyno proven in the sponsors to beat the stock ITR and comptech header on a stock b18c5.

none taken. i relied on their dyno graphs. it was all in one of their articles, dyno graphs and all.. and i usually only believe things i see, hear.. if you read the article it makes sense what they said about heat, back pressure and the size of the collector, etc.. it was a long story..

yes on a stock B18c5 which has higher compression than the B18c1. a 2.5inch collector is much better on B18c5 but wont help a low compression stock B18c1.

The compression of the C1 is not all that much lower than the C5.

What headers were "tested" and how was the testing done?

 

I just bought a used Greddy header for my 97gsr swap..how does greddy compare to hytech replica?? i just figure since greddy is a brand name..i figure it would be good for performance..

 

The Greddy is decent from a quality standpoint, but isn't going to perform much differently than any of the other "bolt-on" headers with 2" collectors.

 

For best stuff go for jdm itr header .............if your car is lowered it don't dent the bottom that much .......good lucky

its a header, neither one will really affect reliability. i have a megan racing and it does fine

 

i got a t1r header

its a great header, you can retain the cat, as long as you get a jdm itr one, or an aftermarket test pipe like the 2.5 inch t1r.
for the price you buy a jdm itr header, you might as well get something much better for a little extra. just my opinion
