Which header do you think is better over all the HP racing header w/ cat or the dcsports header? and which header do you think give you more hp?

the HP will give you more but if im not mistaken its not legal as far as emissions go. I know here in Tx i cant have it on and pass emissions

The hp is one of the best for our cars, I have it, but I don't have emission laws where I live yet. So, I guess your stuck with getting the DC or any other shorty header. I had the DC before I got hp and I couldn't tell a diff. with the DC in power. So I sold the DC and I couldn't be more happy with the Hp.

Rob,
I would go with the Hp Racing header as long as you don't have to worry about emissions in Warner Robbins. If you do, go with just the Hp upper section. That way you keep your cat and pass the emission inspections

i have va tags and have to worry about emissions until i transfer my tags... i think what i'll do is go drive to va when i get home, get my emissions done, drive back to ga and throw on the hp header along with a nitruous kit.. im still looking for a good one to get.. do you have one? could you help me put it on?

we don't have emissions in Indy so Im not worry about it. I went to the HP racing web page and it said it only for the 01 civic is that true or will it fit on my 02 civic? thank you everyone for your help

Go with the HP.

If you have the EX and get the HP, then you only get the top part. Is that correct?

Yeah, it fits 01-03+

any shorty header you get will have very minimum gains (1-2 HP)unless you have the downpipe to go with it...that's where all the power is. I have DC header and an ebay downpipe but i didn't install yet cuz i didn't buy the o2 sensor yet.

how much of a gane will you get with a downpipe? how much of a gane will you get the the Hp header/cat?

you can get the full racing header if you have the ex( you just have to shave a liitle piece off the bracket of the motor mount. It's really no big deal. As far as gains, I say maybe 8 or 9 (don't quote me on that) at the crank. Maybe even more because I could tell a pretty big difference. The stock cat, along with the stock intake manifold kill the performance of our cars. You replace those, your doin' something.
