Great video with the dyno graphs...My car has EL but I love the sound of UEL, I have a set in the garage ready to fit but I really don't want to mess with the engine performance..
Unequal length headers were common on Fox body Mustangs 5.0s, so I don't understand why people associate the rumble with boxer engines. That's why oldheads like the sound of WRXs compared with the exhaust notes of other hot hatches.
yup, maybe the effect of UELs are just more pronounced with boxer engines? especially 4 cylinder ones since they don't sound like any other 4 cylinder engine out there
People say equal is the way, but in reality with flat plane engines where you have cylinders firing in pairs the ideal is to have a slightly unequal header so for example the gases from 1-4 don't collide in the pipe at the same time but instead make one tightly follow the previous one and create maximum flow, so instead of having 2 explosions fighting with each other which one will pass the pipe first at the same time and be depended on the vacuum of the previous pair's gases ending up creating back pressure, you get 4 guys following as 1-4-2-3 chest to back. With equal 4-2-1 headers the thing is a little better as it is due to the usually bigger size of pipe merging into one but still i'd rather have maxinum theoretical flow and rumbly sound. With unequal headers you can gain more than you lose, you only lose if the gas travel is unecessary long and not because it's unequal.
An exhaust manifold is not the same as a header. A there are two headers on a v8 that then connect later down the exhaust. There is one exhaust manifold on an i4 that collects all the exhaust from all the cylinders and combines them immediately, usually before entering a turbo. Not the same thing because one does not combine all of the exhaust while the other one does.
Dont forget there are some really good uel headers that make way better low down torque than EL headers I'm in uk and there are people running nearly 700whp with uel headers and no problems in decreased engine performance
Unequal length headers mean the exhaust is not scavenging properly which reduces efficiency and is what creates that “rumble” you describe. It doesn’t hurt the engine, but it does make things somewhat less efficient, so you are leaving some potential power untapped.

I have EJ204 NA engine on SG Facelift Forester streetcar . For NA engine which header is better for performance / fuel efficiency ? EL stock header or UEL header ?
you'll definitely get better performance and also better heat management with EL headers. The benefit of UEL headers is mainly just the rumble (which some people I know don't like anyways lol)
As someone with a tiny bit of subir experience, when you just rev it the rumble doesn't really come through, when driving hard and under load is when it really shows up
i would say the cons of header wrap are quite minimal in comparison to the benefits so i would rather get header wrap on mine, especially since the headers on EJ engines go around the oil pan, filter and spread a lot of heat into the engine bay
hmmm, personally I'd get the unequal since the NA probably won't benefit much from equal length headers, and it'll sound like a usual 4 banger. the uel makes it sound a lot nicer. I also still have the tomei uel on my sti lol, just can't stand the equal length sound
I’m torn.. My 03 Bugeye is ready for a clutch due to a failed slave cylinder, as the piston was binding in the bore, causing half engagement. It takes 45 minutes to yank the engine, Vs 2-3 hours on my back to pull the trans. So decisions on Headers… My concern with my decision is Heat on the right bank.. I have a buddy that works at the dealer, and he said bore wear on the right rear cylinder is always more than the rest due to heat.
Yup that's correct, the 4th cylinder is always the one most prone to damage from heat. An equal length header will definitely help keeping the temps down, but installing heat wrap would also help if you want to keep unequal length headers. Additionally, you can also get a "4th cylinder cooling mod" from GDT or Torque Solutions to further help with cooling. I'm running the Torque Solutions one with a Tomei unequal length that is also heat wrapped. Personally I really like the Subie rumble so I want to try keep it while also improving reliability lol. Hope that helps!
The common ELH on a Subaru is designed much like a tri y header on a V8 application. The common UELH is akin to a set hybrid longtube/shorty race headers. My opinion is that both designs are lacking, however they get the job done. An equal length 4 into 1 is going to be the best bet, overall. Now with this being said, and yes this is the unpopular opinion for sure, I believe that marketing has it reversed: I have personally found that UEL headers in a Subie application makes MORE top end hp than EL tri-y headers. Of course, EL 4-1 will make more than both. I have another unpopular opinion, albeit for intake manis.... one of the best oem intake manifolds for the EJ, if not the best overall, is the black plastic 08-14 wrx intake manifold. This is from a dyno perspective, not flowrates alone.
so im confused, whats better for performence? uel or el? also i heard that on the brz you need an uel to fix the torque dip at high rpms. is that true and will it be even better with el?
Are you on the stock turbo or is it an aftermarket? I'd recommend you take a look at the Grimmspeed headers, they have a mix of the higher equal length pitch, and the classic boxer rumble.

I don't exactly know either, I'm guessing it would have a similar effect where the sound has more of a rumble/rougher sound. One example is the twin turbo I6 S55 engine where the length of the front and rear downpipe is about a foot and a half apart, this is why the sound of the F series M3 and M4 sounds more like two inline 3's since 3 cylinders go into one turbo. Try search up "S55 Equal Length Midpipe" and listen how different they sound.

Twin scrolls are not good for hill climb attacks with equal lengths headers. Single scroll are alot better. Listen to Flatiron tuning. They explain it better.
There are flat plane v8s which create their own natural sound. Then there is cross plane, we all know that sounds. Then you can put a 180 degree header on a cross plane and get more of a flat plane sound. X pipe vs h pipe noticeable different between those two sounds too
I guess for 4 poppers that want to sound like the big boy V-8s there is always the option of intentionally unbalanced exhaust. For this that truly care about power it’s all about equal exhaust pulse spacing.

Not really done much research into any of this, but how would this work (if it works at all) with different engines? (I3-I5-I6)
I don't exactly know either, I'm guessing it would have a similar effect where the sound has more of a rumble/rougher sound. One example is the twin turbo I6 S55 engine where the length of the front and rear downpipe is about a foot and a half apart, this is why the sound of the F series M3 and M4 sounds more like two inline 3's since 3 cylinders go into one turbo. Try search up "S55 Equal Length Midpipe" and listen how different they sound.
@@JCMediaYT yeah I found that out, and it’s pretty cool. thanks.
@@JCMediaYT wow! I saw something similer (ish) done in an E36 or an E46, but not like that, that’s pretty awesome.
@@isaacsrandomvideos667 ah I've just checked the e36/e46 ones, that's pretty cool
@@isaacsrandomvideos667 yea of course man, no problem! have a good day
Does anyone remember Mesa headers they were unequal length tuned headers utilizing three maybe four different primary tube diameters. The original owner of Mesa headers is an old friend of mine I'm trying to find haven't seen him in years his name is Mike. If anyone who reads this knows him please leave a reply here for me I would really appreciate it thanks
Unequal length or bust. What's the point of dealing with the massive pitfalls of Subaru ownership if you miss out on the best part?
All subarus sound exactly the same so what's the difference
nah not really
@@JCMediaYT lmao listen to your own video😂
@@ericwieboldt7042 yeah? they literally sound different with equal length headers vs unequal length headers. I have no idea what you're on about. The JDM STi's come with ELHs from the factory, and the new FA platform only comes with ELH.
@@JCMediaYT anyone that uses the word literally out of context is not to be taken seriously. Better luck next time though. They all sound the same, like, literally👎
@@ericwieboldt7042 lmaoooo get your ears checked man, you must be on some shit to say they all sound the same considering no one else is saying that 😂 Oh well thanks for the views though!
Am I the only one who gets very annoyed by exhaust sound clips where they just sit in place and don't rev past 3k rpm?
You didn't specify that even length helps inline engine, but not v. Scavenging is a myth in equal length v8s.
Unequal all the way! Equal wrecks the sound.
My 99 Grand Prix with the 3.8 V6 has unequal length headers factory due to it sitting transversal. But it sounds so bad and raspy. Literally sounds like wet farts
That civic sounds like a lot like Subaru👀
yupp, shows how most of the boxer rumble is caused by the unequal manifold lengths
Twin scrolls are not good for hill climb attacks with equal lengths headers. Single scroll are alot better. Listen to Flatiron tuning. They explain it better.
I think I speak for everyone here... Unequal is what we want🤣
What about v8s? I heard flatplane v8s with uel header sounds like a classic v8 sound not a subie
do you have any clips of flatplane v8's? never heard of them myself. could be due to the header design and the firing order but i have no idea either.
Modern mustangs
Dude there’s twice as many cylinders. And the unequal length on a v8 has every cylinder a different length from front to back
@@JCMediaYT The GT350. Flatplane crank V8 with unequal length headers
There are flat plane v8s which create their own natural sound. Then there is cross plane, we all know that sounds. Then you can put a 180 degree header on a cross plane and get more of a flat plane sound. X pipe vs h pipe noticeable different between those two sounds too
Would much rather have greater torque and performance over a certain sound.

I guess for 4 poppers that want to sound like the big boy V-8s there is always the option of intentionally unbalanced exhaust. For this that truly care about power it’s all about equal exhaust pulse spacing.
all down to preference hehe. boxer engines with equal length headers scream like crazy though
Unequal length headers make your Subaru sound like a riced up Honda Civic with a dead misfire on one cylinder. Apparently some people like that sound.
Why don't SUBARU owners convert to "Equal Lenghth Headers" as they could gain better MPGs...
My brz is so underpowered already. I wouldn’t put equal lengths on it anyway
the solution is forced induction hahaha, they're great fun to drive though
mantap gan, lebih suka uel
Equal length with EWG sounds best from an Ej.
I am heavily considering switching my Tomei UEL for an EL header lately
Unequal sounds better
Why
the civic sounds more like a subaru than my subaru
same :(
Funniest thing, is in n/a engines, especially prone to exhaust changes. You lose 2bhp on header, and get 2,5hp on pipe and muffler xd
So the POWER is really crazy xd
One sounds better the other performs better
pretty much yeah
Your V1 detects laser buddy
what?
That fucking civic sounds like a Suby lol
Choose carefully:
cool sound but good performance
cooler sound but lost performance
I see that tf2 profile picture 👀
