What Header for Performance

[vitti821]

Hey,
I am sort of new to the mod scheme of the BRZ, and I am looking to replace my stock header. So far I have done exhaust and that really it for mods. ANy suggestions on what header to get.
What I am looking for in header:
- maximum performance/ HP gain/torque increase
- sound increase doesn't matter because My current exhaust sounds good enough
- reasonable pricing because I am not loaded
Thanks for your help

Do you prefer EL or UEL?

What's your current exhaust set up?

whats the difference between uel or El and I have Invidia N1 catback

[Freeman]

Well for my tastes the N1 is too loud with a header but that's all personal tastes and local laws.

EL is equal length runners on the header

UEL is unequal length runners on the header.

Here is a good place to start.

ok thank you, UEl or El doesn't matter to me, Just looking for a list of headers that Give significant horse power boost

[shellslinger]

The consensus lately is to get the ACE Header. They seem to provide the most hp/tq for the header. However, to maximize these header along with any other header you would need a tune. Appears that the only tune at this time that will maximize the gains of the ACE header is the Ecutek tune.

here is the link to the thread w/ dyno results:

as per above thread "basic Bolt on mods guide"

Their is not rearly much difference in catless EL/UEL just pick your sound you like UEL gives the boxer rumble.

For the street UEL usually give a bit more midrange so its usually better where your using the engine most

For arround $700 you can get a good EL/UEL header Tomei Gruppe-S Openflash OFH or similar you will get about 20hp gain with tune

Or if you want the best performance probably the ACE header but its arround the $1400 mark maybe 5hp over the others

Whatever header you get your going to need a tune, else most of the gain will not be available and you will throw CEL code P0420


you need to look at a header and tune package.

If your not loaded then just get a reasonbly priced header like tomei , gruppe-s or openflash header.

for cheap tune your looking at an Ecutek Flash and Go tune (canned ) tune these are about $600 (Ecutek licience plus tune) IF you have a local ecutek dealer to flash the tune. If you dont your up for another $400 for a cable to flash.

Other option is the Openflash Tablet, device to flash tunes that comes with a selection of tunes for EL/UEL 91/93 fuels and E85 fuel. Its $500 and you flash your own tunes whenever you like.

They do a Tablet/tune and header package for about $1100 if you want uel header

unless you have a quiet catback any catless header is going to be quite loud, if you fit a header be prepared to put your stock catback back on if its too loud, the stock catback is not restrictive, it just does not sound the best but it is quiet.

you can then sell your aftermarket catback to recover some money

I ran a N1 and a PPE equal length merge collector, the car went over 200hp on the dyno and 13.47 in the 1/4 mi.
Videos are on this site in the 1/4 mile time thread or go to youtube type

I was on E85 still am and yes very noticeable. The car ran 15s factory, mods to the 13.5 that's a lot. You have to get a tune with a header have to or it runs like poop.
Go drive a new SI civic and that will give you a idea

Those two are mutually exclusive.

If you want the best bang for your buck, gut the cat out of your stock header. If you want the best performance, you want an Ace 4-2-1 header.

Don't forget to budget for a tune, or you'll only really get a change in sound with a minimal change in power. You need the tune to prevent a CEL, and maximize the gains.

Is this all the mods you have? I have trouble getting under 14.5 @ 96. My best being 14.3 @ 97. I have borla UEL, catless fp, e85, ecutek by HRI tuning.

13.5 is damn impressive. Are you on slicks? Very cold weather? I'm in Florida so it is warm even now.

Edit: I see you have gears and slicks. That's probably making the difference. Agree? Since I can only do a 2.2x maybe 2.15.
