EL vs UEL headers
 

I see many people on here prefer UEL headers, but honestly, wouldn't EL be better? Seems to me like the flow would be more even and result in better fluid dynamics.

I am no physicist, though, so I could be way off. :P

EL does flow better, UEL gives the boxer rumble which many people like.

Ah gotcha. Thanks! Does the EL sound bad or just not as good as UEL? lol

Different. The EL sounds 'racier'. More like a regular 4 cylinder.

Is there such thing as a audio clip or youtube of a stock 86 with just the uel header? Most clips i find are ones with exhaust and other mods.

Looking for this too

edit - Found it. This is from the linked thread.

That... doesn't look like stock exhaust to me, but it might just be the camera angle.

The tips are too round to be stock and the muffler is too shiny to be stock.

UEL vs EL has come up several times. Not seeing a very massive difference between tuned UEL vs EL sub 300 whp. Very minor if anything and not noticeable. It comes down to, can you sacrifice anywhere from 3-10 whp (depending on FI or not) for your boxer rumble? That's literally the difference you're going to see running UEL instead of EL.

EL would be a must for the stage 2+ turbo kits pushing above 400 whp or someone who wants to squeeze every ounce of hp they can out of a part. Even then, no one can tell you that you can't run a UEL at that whp level.

Err.. okay, so, dmittedly, I have no experience with H-motors (boxers), but in a typical I4, you would be ditching the header in favor of an exhaust manifold when going turbo... how does this work with a boxer motor since the ports are split into 2s, with each duo on oposite sides of the motor? In a V6 or V8, also with split cylinders, you would twin turbo teh SOB and call it a day, but that would be overkill on this tiny motor.

I don't have much experience with them either as this is my first run with one. I've just been comparing dyno charts done between headers. Turbo manifolds are very similar although ones like the P&L Header, or the FA20club manifold is a hybrid header (NA or FI) based on a V-Band clamp that wraps in the front determining where the pipe goes. The longtube design has also produced pretty substantial numbers tuned.

UEL (mine is borla :/ ) lose the rumble as soon as you go FI except at idle. Just an FYI.

Whats wrong with the borla uel header? I felt like it was most popular so felt like i would go for it /shrug
Whats the best one then? Most people ive seen at meets got the borla :bonk:

If you haven't bought it yet, I'd go with the JDL (if your going FI) or JDL or revworks if your staying NA, the issue with the borla isn't the QC (though it is horrible, and mine is rusting after 2k miles on it (collector housing and weld joints) but the true issue with the borla is the collector is complete crap, no R&D went into it, so it's 4 tubes arc welded togeather with no merge flow. And I believe it is stopping me from having a really nice linear progression on my dyno. (See FI area, moto-east tuned vortech thread.)

If you have bought it, well if you go FI I think you'll be replacing it like me.

Borla is the cheapest and worst built when comparing to Rev Works or the JDL UEL. The Borla collector is crap compared to the other choices. The warped flange issue has been fixed, but it doesn't change the fact of "You get what you pay for" when looking at the collector.

Didnt understand what QC is or R&D.
I dont see myself going FI. At least for many years :brokenheart:

There's a picture somewhere on the forums (can't see because I'm at work) that shows the collector side by side with JDL and the Borla. Looks like a 5 year old welded the Borla one.

Quality control and research&development... Both are the most important things to any good company out there.

Yeah I got to go find it and make it my sig, I don't want anyone to suffer like me.

Here's a nice and big one... it's my Borla header:

Holy cow that looks terrible haha

sorry!

Here is a photo of the PPE EL Header Collector. Sorry lighting isn't the best, but some light photoshop makes it clearer. I like EL.

The Second Dyno Clip is our header on a 100% bone stock header back exhaust. Only mod was the Header

Thanks for the kind words guys :)

@Rev Works, I'm not blowing you, any vendor that does quality work should crush those that don't.

:clap:

You are right though, I will be replacing my borla eventually.

Props to @Rev Works for also doing an untuned dyno as well so you can see what a header does on its own so you aren't seeing bloated numbers like a tuned e85 header or a pumpgas tune right away. Stock tune shows gains, then the tuned version shows great gains.

Keep up the good work! This is the kind of information/customer service/quality parts we like to see.

That's a nice collector as well. You can definitely tell Borla is in it for the money, not the quality product. How many can you produce in MASS versus how many GREAT headers can you make to make your customers happy? This is why I support shops like Perrin, Nameless, JDL, and some other great ones that I forgot to name. They take pride in what they make, take time to research it, and don't release crap welds like that collector. Sure, it takes more time to get products for them, but you have to realize, a lot of these parts will be on your car for many years to come unless you part swap often. I'd take the time to wait for something to be welded to perfection before it touches my car. I don't like sloppy products.
