header help

[willieg123084]

iwas wondering if OBX and Megan headrs are just as good DC-Sport headers and if they sound the same

[blackcb7]

if i were to choose i would get the megan, people say that is the best bang for your buck.

if you live in a state where you are not required to have carb legal parts then i would suggest you purchase the megan since they are cheaper

if you live in a state where carb legal parts are required like california, the go with the dc sports

[rickyduckworth]

i'd say to waste money on neither, find the stock header from an f22a4 (90-91 ex/se) and call it a day.......as far as power goes, the a4 header is just as good as the dc or any other affordable header, just not as pretty, although you could polish it. the f22a1 and f22a6 doesn't have a header so no use in bother with those if you're looking to upgrade.

[deevergote]

DC is only good for the carb label. Megan is the best affordable aftermarket header for the F22, though the A4 header really is quite good. For real performance, the Bisimoto header will be your best bet.

So:

DC if you want aftermarket and live in CA.
Megan if you want aftermarket and don't live in CA.
F22A4 if you don't want a pretty aftermarket header, since the performance will be similar. Since it's a stock piece, it will be legal in CA.
Bisimoto if you want power and looks... and are willing to spend $600 or so.

Are these A4 headers really just as good as aftermarket?? Cause mines looks like its been through a war. Its only natural for me to assume that it wont perform as good as aftermarket ones..

[Dani Filth]

are they dented? bent? rusted through? leaking? if not the appearance doesnt matter. they may look like crap but they work. if you care about appearance get the megan racing ones. the a4 header is a tubular design. it flows well. it was designed by the honda engineers. the aftermarket headers are generic designs. they arent designed for the engine in any way. just mandrel bent tubes arranged in a formation that should work. if you look youll see its probably very close to the a4 design. the aftermarket ones may have slightly larger diameter tubing and maybe a larger collector. but it wont be that much of a difference. if you gain 5hp over the a4 header with a dc header id be surprised.

I'm new to the cb7's. I just got a 91 EX and after reading how good the stock headers are I'm thinking about polishing them instead of buying new. I was just wondering if it's ok to just take the heat shield off and leave it off or if it's really there to protect something.

[Dani Filth]

its there to protect the plastic parts and electrical components but nobody seems to have any trouble when they remove it. if you polish it it will rust easily. youd have to maintain the polished state regularly. shop around for someone who can powder coat it if you want it to look nice. get the shield done to match even.

from my own dyno pulls, on a stock engine, the dc header made 1hp LESS compared to the a4 header.....same with an h22a, the jdm header makes the same hp as the DC header.....

most DC headers have a generic design and aren't worth the money compared to REAL headers that cost $200 or so more.....

DC headers seem to benefic the civic crowd more, which is where they actually made a name for themselves.....people confuse DC with a true tuning company, when they aren't

nice info, I may have to go buy me an a4 exh. manifold. thanks.

well good luck, since there is no such thing as an a4 exhaust manifold....


an exhaust manifold is a cast iron piece that is one piece....the a4 has a true tubular header that is made from pieces of tube welded together and it's made from steel.....there is a difference......casted pieces usually have casting flash and less specific dimensions...they're usually porous too....

no shit, it's actually a tubular header design? even better. thank you.
