4-2-1 or 4-1 headers?

[evan_mph]

which configuration is better, 4-2-1 or 4-1 headers?

furthermore, is there an ABS kit for the CB7? is it worth it? Can someone give me a link to view, research on, or purchase from?

sorry for combining 2 different topics in one thread.

ABS kit?

I'm taking it you have a non-ABS Accord, so that means a 90-93 DX/LX (not including 93 LX 10th anniversary edition) and/or 90-91 EX.

If there was such a kit, it would be ridiculously expensive. Have you priced out a ABS modulator?? Craziness, the ABS has it's own computer, etc. Anyways, it'd be cheaper to sell your current CB7 and get a 92-93 EX, 91 or 93 SE, also the 93 LX 10th anniversary edition.

To get my point across on how expensive ABS Honda OEM items are, check the following links. That is why it would be cheaper for you to located one of the specific models I listed above with ABS already.

Just look at the ABS modulator and accumulator

header

A 4-into-1 Header with a fine-tuned collector is the best for peak power. The real only problem with the 4-into-1 is 1. ground clearance (cause of the collector) 2. Getting them in is a pain in the ass.

In the US, only the EX's and SE's came with 4-2-1 headers.

LX's and DX's came with 4-1 headers..

i wounder what kind of header would be best for me.
i want the most power between 4000-7000rpm?.
below that i dont care.
i also wounder what the shippmentcost would be to sweden?.
whats the correct spelling, shippment or shipment heh?.

[HondaFan81]

shipment...............

hmmm i was under the impression that 4-2-1 is naturally better than 4-1

[accordaffair]

also, majestic honda is def. not the best place to research prices. Their stuff is all new, 700+ for an ecu? trust me you can pick one up for 10-100 and never anywhere near those prices. used, of course, but what I'm getting at is majestic is prob the best place if you're looking for who has the HIGHEST prices.

i have a DC sports 4-2-1, and i love it, i havnt tried a 4-1 but i raced my stock LX vs. the same LX but with a kamikaze header and i took him, but those header(s) were our only bolt ons....

Patrik.johnson: The basic tuning theory of small diameter long tubes for torque and larger diameter short tubes for High- RPM Horsepower

Accordaffair: it depends on your step up but with a GOOD 4-in-1 header vs. a GOOD 4-2-1 header you are only really looking at about 3 to 5 horsepower difference between the two in fav. for the 4-in-1. However the engineers at Honda knew what the hell they were doing that is why it is so hard to get horsepower out of are motors with out throwing on a turbo, supercharger, or Nitrous. not to much power was left on the table. compared to a V-8 where you throw headers on and you can get a lot of horsepower.

In the end just make sure you buy a GOOD header, don't buy a no name brand. Go with a brand that you know has done their homework, look at the build of the header are the lines and welds smooth or all rigid and ruff. You get what you pay of.

ya lol. put some headers on a small block chevy and you'll get like 20 hp. And then the intake manifold could get you like 30 hp.



All figures are guesstimated and are probably not correct.
