Can't decide which Header to get
- Thread starter mini_FD

are you sure it's JUST an axleback? Does it run up to the 2nd cat?
I know a guy down in Jupiter that is selling a 3" high flow midpipe, but, unless you plan on boosting, 3" exhaust will actually hinder the car more than help.
If you don't like your HKS, i'd say sell it and pick up the racing beat catback
Then, with the Ractive header, you can look into a 2.5 or so high flow midpipe.
One question though, do you do a lot of highway trips? Cause with the header, midpipe, and exhaust, the drone is pretty bad on the highway

If you're just running an exhaust tip or HKS axleback. Go to your nearest local exhaust/muffler shop and have them put a 2.5" straight pipe from your header all the way back to the tip or axleback.
You will notice a bigger drone in the exhaust like others said. There's no need to buy another name brand exhaust. If you were completely stock, then i could suggest you buying another exhaust.

hey, i was just reading through this thread and wanted to add a couple things, I have a j-spec fs-ze with the japanese sport 20 ecu , its a very nice motor, and for those who say that the fs doesnt respond well to mods, well its given that it might not respond as well as a honda b-series motor, but it does respond. I have a couple friends with sport 20 hatches here and their motors are modded, they do respond well, and noticeably so, to IHE mods. Anyway, if anyone is interested in a FS-ZE ECU, let me know i might be able to source one, but remember, just the ECU, no harness and that ECU is OBD1 only...I'm really sure i can get it cheaper than anyone in the US... oh yeah, the FS-ze come stock with a 4-2-1 header, but my friend has a obx 4-1 on his and say he did get an increase in performance from it...

Monday first thing i'll do is go to a muffler shop and ask them the questions and get back to you with the answers so we can decide then. and i rarely make trips highway so i hope city will be fine. what's the con
I basically looked up what exhaust was available for the Protege/MP3. And they have a HKS axleback that fit's on the Protege5 wagon. You probably have the tip, maybe a axleback. Regardless get some custom piping done!
And to ghostbusters: No one said that the FS doesn't respond to mod's. All car's respond to mod's. Your basically freeing up hp that's already there, just don't have the oommphh to free up as much as other contenders.
What I'm saying is, i think spending 1K on a FS to gain 15-20WHP is a joke. A B-series, K-series, 2ZZ-GE motor doesn't take much to gain anything. A Raceheader and Intake alone net around 15-20WHP on a RSX Type S.
If I'm spending that kind of money on a car doesn't matter what it is. It's not worth it to me. To even go that route. Best route to take on the FS motors is to go F/I

i get wat ur sayin, dude could u de-bold my name, lol, that is bright, i really am trying to build a NA motor though, willing to go all out, next step is autoexe header(4-2-1) then full exhaust and this week i'm getting an intake, its a start
i Feel like such a noob. explain the ecu again i didn't understand all of it and i was checking out spicy orange reflash ecu and still waiting to get back on how it works on the FS-ZE. anyways i'm going all motor as well but the auto exe header is 1000 right? correct me if i'm wrong because i thought i saw it for that much.

the important thing to know is that u cant get the full potential out of the fs-ze with either the mp3 or ordinary fs-de ecu, u need a fs-ze ecu to get the 170ps that the motor is capable of making.Yes, i think i saw the autoexe header for 1000, which i dont intend to pay, where i'm located we get alot of jdm cars , front halves and engines so its just a matter of sourcing a used header, it'll take sum time, but i'll find it. I dont know for certain if the wiring harness is the same for the fs-ze and the fs-de, i can source a fs-ze ecu , but i may not be able to find the wiring harness, so u'll need to verify whether or not the wiring harness is the same, and if ur in a state that requires emissions tests, since the flash is different, i could not say whether or not u'd pass...i can check out the ecu and let u know how much one would cost

yeah, it would be reliable, mine is and so are the ones that i know of here, (3 other sport 20's) I dont think its possible to unlock the car's full potential by a simple re-flash, probably an aftermarket fuel and ignition controller might help, but i cant be absolutely certain.remember u'd just be using the ecu that was actually designed and programmed for that motor, which ur currently not doing.

ok i dont think u get this so im going to say it...with out the FSZE ECU your car is almost exactly the same as the regular FSDE power wise
if your going all motor and your going to be doing cams, cam gears, ecu, lighter pulleys, port&polish all that then i would go for the 2.5 like whats his name said up there^
bt if your just going to do intake, header, exhaust, get 2.25 so u dont lose so much torque, if u get the 2.5 anyways well then ur going to have like 2whp more and 3ftlbs less
if ur going NA then i would go all out, get the 626 mani or remove the VTCS from yours, jdm cams..u might already have those lol, port & polish, lighter pulleys/underdrive pulley, header. 2.5 back WITH HI FLOW CAT, if u do not get a hi flow cat your car will sound like a piece of s***, this is coming from experience, intake (CAI or SRI, they both give the same power)
thats about it, oh and the MP3 ecu reflash and u should be at a decent amount of power...maybe 150ish whp?
edit: i was talking about exhaust diameter up there when i said 2.5 and 2.25
