UEL headers for BRZ
 

Hey guys
So I have a limited BRZ and want to put uel headers on it before christmas. I currently have an invidia n1 catback and a perrin cai. I was wondering if there are any upgrades/mods i have to do along with the headers or if i can just install them.
I also plan to tune it soon after headers, im thinking of going OFT. Any suggestions for the notorious Scooby rumble + deep sound?

You can certainly just bolt and go but to get all the "benefits" of a header, you need a tune. If you decide to go with a catless header, you will need to deal with the resulting CEL, which the OFT will take care of. I currently have the Tomei UEL header with the OFT stage 2 tune and it really wakes the car up. :D Are you in Sparks, MD?

If your going the oft route then look at the oft plus open flash uel header combo, tunes optimised for that header included and you get a discount for package deal.

any catless header is going to be pretty loud with an N1 catback though,

maybe read the Basic Bolt on Mods link below

I have the Tsudo UEL header which I use with an OFT stage 2 tune. I haven't had it dyno'd or anything so I can't tell you if it's better or worse than the OFH, but it does register nicely on the butt dyno along with the OFT tune. The header is only $360, and if you email them, they will likely honor a 20% off coupon that just ended 'TSUDO20'.

There are sound clips and pics in my first post:

I want to do headers rather than bolt ons, im just unsure of the whole process. Im new to this whole car mod thing. Theres a mod shop that can tune in town but idk which way to go with it.
How does the tomei uel sound? I dont really mind how loud it will be, i actually want it to be louder and hopefully deep scooby rumble with no rasp. How does your setup sound?
And no, im in sparka NV

A header (not headers) is a bolt on. I posted a sound clip of what mind sounds like in my prev post. Yours will obviously sound much louder, and probably raspy.

Should not be raspy, i have n1 and UEL headers without rasp.

Ive been lied to my entire life... Whats the difference between a header and bolt ons?

Which uel do you have? Does it wake the neighbors? ;)

i have the gruppe-S uel header, pretty similar to the tomei's... on cold starts it is very loud lol but no one complained yet! Its only been 3 days though.

I really don't think there will be much difference between any of the vendors UEL headers as far as sound goes (as long as you are comparing catless vs catless) Here's my setup which is stock exhaust except for the Tomei UEL header, TRD drop in filter and the OFT stage 2 tune. Cold start is loud due to the tune (heating up the cat in the front pipe faster) but other than that, it's pretty quiet. Halfway thru the clip are some revs so you can hear the "rumble".

I'm sure if you search long enough, you can find a clip of the UEL header and N1 catback combo.

Parts that can be easily bolted on with a ratchet/wrench etc.

Edit: Sorry, I explained what a bolt-on is, not what the difference is. There is no difference because a header is a bolt-on.

For example, a header.

You know, I'm not exactly sure where the line is anymore. Basically anything is a bolt-on the way I look at things.

I guess a bolt on is easy stuff, where as suspension may be a gray area (not hard but a bigger project than a header or intake), engine internal mods are not bolt ons.

Anyone able to help me out here..... i know its probably a stupid question.

If I plan on going Turbo down the line but want to install headers before then are there specific headers that are set up for the turbo install or will you need a new/go back to OEM header when I install the turbo? I know some turbo kits do not come with headers and just install on OEM parts, but if i have an aftermarket header already will the turbo still install fine?

I don't think any of the turbo setups work with any NA headers, aftermarket or stock. It would require some serious piping creativity. One way or another you're always replacing a minimum of one exhaust component. Otherwise where does the turbo go?

Ptuning's kit "utilizes the factory catted header as standard" quoted from their link on the turbo kit. Wondering if that means aftermarket headers would work as well, I'm currently deciding between jdl and tomei

Yes PTuning's kit will allow you to use any header including stock. WORKS is another one as both kits route after the header so you can pretty much use any NA model you want. But that's about it for active kits, any others will come with their own.

Perfect, thank you. Now I need to figure out how to get the parts all the way to NZ :(

Headers that very unlikely to work with p tuning or works kits would be Nameless PLM or ACE header
