Borla UEL headers w/stock exhaust VIDEO
 

[ame="http://www.youtube.com/watch?v=7ZM5d_7c5Xo"]Borla UEL headers with stock exhaust - YouTube[/ame]

Had them installed yesterday by Peter at Exhaust World in North Perth who did a great job. I provided spacers for the O2 sensors (HELP 42009 spark plug non-foulers) which have (so far at least) stopped the CEL issue from having no cat.

The torque dip is more like a plateau now and seems to pull a lot better, but let's face it, the main reason for UEL is boxer rumble! :party0030:

Not sure on what to do for the rest of the exhaust but it is likely that it will be an Invidia Q300 and then a custom down and midpipe :)

I will post up another video after a month or so if there is any change to the raspy start up noise. I suspect it will quiet down on start up after it has got a bit of carbon in there :)

On a cruise recently I opened her up at freeway speeds and will post up the in cabin video of that shortly :)

There's not, that's your car warming up. Keeps the weird rasp on every warm up.

Never put a spacer/anti-fouler on the primary wide-band O2 sensor! The ECU relies heavily on this sensor to adjust the AFR. The secondary O2 sensor is the one that monitors catalyst efficiency and requires attenuation when the primary cat is removed.

A CEL will be thrown othewise. Until I tune the engine this will be the solution. 1000km and no issues so far :)

The exhaust in the video doesn't look stock. Did you mean headers with stock overpipe/frontpipe/midpipe and axleback?

he's from australia, they get the 86mm tips.

Ahhh I see. Didn't know that :/. Wouldn't that make a big difference in terms of sound/drone/raspy/etc comparing it to ths US 86?

Good luck with the "lean burn" AFR mod. The hydrogen fuel cell and high MPG guys are pretty big on this mod too. Just be careful that you don't let your EGT get too high while running such a lean AFR or you might melt a piston. You will lose power this way but gain mpg so if that's what you're after, good luck with it.

Woah I thought I was in a game of COD when the car started lol.

This....

Put the sparkplug defouler on the O2 AFTER the Cat...not before. Even if you throw a code for the Cat you wont run lean.

It's hard to tell from the video; how much louder did the car get vs. stock?

It got a little louder, but mostly under load. When idling it seems to be quite normal but can still make out that rumble :)

Sounds really good.

LazyZed.... do you have a video of the car accelerating from in the cabin and drive by?? =)

I get the CEL every now and then because of the headers. It only stays on for about 50 to 100 miles and then resets itself and turns off. Comes on about once a month.

I have not processed them off my Blackvue camera yet. I will be going through some footage and will post it up here when I do.

Sounds a lot better in the cabin than it did when I first got it done and you can really notice the noise under acceleration onto freeway on ramps :burnrubber:

the rumble is more pronounced, but the volumes are barely noticeably louder. thought id be happy with the uel manifold and stock catback only.. didnt last long at all. ended up getting a resonated perrin catback. so much better than i would have anticipated.

I cannot wait. I'm installing mine Thursday!!!

Thanks =) looking forward to hearing it

:bonk:You guys make me wanna spend all my money on parts!

$574 shipped to you from Jegs.com...

just saying.

I want to maintain the warranty but I my feelings tell me I want my car to have more power.

Warranty or power hmm, the ultimate conundrum, wait for TRD supercharger even though it might not come?

It wont. If it does it'll be for a different model year... AND it will be 9000+ dollars.

It will be for all of them due to the fact the FA20 is slated to be around for quite some time, and the body and design of this car can conservatively be kept the same for the next 2-4 years without a major body changes (the design looks timeless to me :) ). If it doesn't come in this current version I wouldn't expect it the next unless there is a huge reboot in the cars style and Fuji Heavy Industries gets bought off.

hey just had a question for you on the Borla UEL headers, when you received it what exactly came in the box besides the headers

/sob

I'm pretty sure that one isn't even available to consumers. It's strictly a race team sort of deal.

Bit of threadomancy but do you happen to have any video/audio of this setup? I have another thread asking for best options to go with the UEL header :)

Was leaning towards the headers, but that cold start is brutal...in a bad way:(

Any catless header you get will sound like that on a stock tune and on cold start. You should, as you are supposed to, get a tune to make the proper amount of power and simply tune out that excessive cat warm up process on the stock tune.

A ELH will not be as loud as a UEL header, even at cold start.

EL header is better in every way when it comes to performance though, except for marketing.

Opinions may vary

i have borla UEL+ manzo overpipe+ stock front pipe +q300. Its super quiet.

You can tune the cold start to turn off entirely. Also Borla seems to be one of the loudest headers out there.

You'll never hear that with a tune, which you'll want in order to optimize header gains anyway. I ran the borla v2 with my stock exhaust for a month or so before getting a catback and I'd say it's a pretty mild change to sound overall. It's a little louder but if you weren't expecting or looking for it you might not even notice. The rumble is there if you're listening for it but it's very subdued.

Performance, on the other hand, is extremely noticeable. I'm on the Stage 2+ OFT tune and all I can say is that it is NOT overhyped.

Be careful if you start shopping catbacks after installing this header, you'll be amazed how much the stock system does to keep volume down and kill drone.

O.k, great info. Thanks.
I've put a bit of research into it, and never until now read the tune will solve the harshness during start-up. I drive a lot, love listening to the engine, and concluded Borla UEL, plus a tune is a good next step based on vids (but they all had other mods too). I am optimistic again.
I don't want to replace overpipe if not necessary, what is the advantage of that?

I may be mistaken, but I don't believe there's much point to replacing the overpipe unless you want a 100% 3" system, which only really benefits FI applications.

It's possible an overpipe on an NA engine could be a bit more efficient or lighter than the stock piece, but I assume the differences would be extremely small and barely noticeable if at all.

I'm running a stock overpipe and frontpipe and the Tanabe Concept G catback.
