JDMuscle Unequal Length Header 2022+ VB Subaru WRX - Sound, Dynos and Installation

[@MrSauceman09]

"performed on a closed course" *Absolutely sends it down the road* lmao. Maybe I'll have to get one of these for my '22

[@AlxRayn]

The unequal headers actually made it sound beefy, very impressed, almost sounds like the 2.5L

[@fuludude]

the fact that it’s a 2.4L, rather than its 2.0 predecessor, definitely contributes to those good ol’ beefy notes.

[@JaydenET]

You want STI sound, they need to be merged at each bank flange into 2 pipe’s instead of 4. UEL gives you the rumble but the sequential pair gives you the bass. Reducing the runner volume may also increase spool. Killer B UNholy header is the only sequentially paired FA turbo manifold I’ve seen but never heard. Sequential EL is where it’s at personally, but I understand the love for UEL.

[@HeavyMetalWRX]

Well, well, well. We knew it would eventually come out. I love that "subie rumble" but chasing it on the VA WRX was not exactly a fruitful endevour in terms of power and , personally, i dont think it sounded as good as having a 2.5 EJ. Now with the FA24 already having a much deeper exhaust note than the FA20 i think this is not as bad of an upgrade. I like how they are keeping the twinscroll in mind. Ill be keeping an eye AND ear on this one for sure.

[@Nonx47]

Nice to see ya here!

[@HeavyMetalWRX]

@@Nonx47 hey my man how's it going??! I'm just here like everybody else. I want to know what's up with these headers 🤣

@@HeavyMetalWRX haha yeah ain't that the truth. Love the sound, worried about what downsides will come with it. Wish I could just buy two and experiment like crazy with one. Don't have THAT kind of cash though 😅

[@HeavyMetalWRX]

@@Nonx47 I will say I'm not 100% sold. Unequal length is always something that we need to be wary about on FAs. I don't think you're ever going to get the sound that they're trying to emulate, but there definitely is a market for this header.

[@Nonx47]

@@HeavyMetalWRX agreed

[@SuzukiKid400]

6:36 sounds perfect, great job to that header manufacturer!

[@MrGsxrme]

I think it's important to make a twin scroll header feeding the twinscroll turbo. Uel or EL should both pickup power. My only worry with running these single scroll headers is exhaust pulse is off and can cause back pressure issues with the cylinders fighting each other on each exhaust stroke. Cylinder 1&3 feed one scroll and 2&4 feed the other. Also becareful of not to go to big on the header pipe size feeding each cylinder, you increase flow but loose velocity.

[@JDMRightHandDrive]

I personally love the sound of the unequal length header. I might have to order myself one. I miss that boxer rumble. Great video🔥

[@bigdumbtruck]

shortening the life of the motor just isn't worth it

[@juanticimo]

Hell yea!! people can complain about slight losses in HP when taking the car to the track, but when its street driven only, thats the sound we are looking for, thanks for the video as well as the development of the part.

[@jdmuscleusa]

And it's actually HP gain! with some tuning you can get the torque back too

[@rmblwgn]

​@@jdmuscleusadoes the horsepower gain come from the fact that the new uel header does not have cats like the OEM header

[@jdmuscleusa]

@@rmblwgn plus larger diameter

[@sleeper.simulant7327]

Diameter is only a part of the equation, and doesn’t guarantee gains if you lose velocity, and I’d be willing to bet the stock turbo isn’t big enough to where larger diameter is required. I’d argue the catalytic converters are the worst restriction. I’d like to see what an EL/twin scroll header of stock diameter will no cats can do, I bet it’ll spool a lot faster and make more power everywhere in the rpm band. UEL’s are a “form” mod, not a “functional” mod. It’s all about sound, not performance…

[@nikesbeast]

Damn this chassis can handle way more torque than the 2015+

[@weeb0.]

That's why I'm sad there's no STI ver for it

[@weeb0.]

(not counting the tS)

[@aregaminghd]

@@weeb0. honestly i feel like people are irrationally upset about there being no VB STI. sure, we dont get the famous STI driveline with DCCD. really, though? that's all we are missing

[@stormblessed9455]

Yeah agreed on the STI point. It's the best WRX to date. However, low steering feedback(floaty), weaker transmission, and the pads and rotors are very prone to fade. Even still, my WRX is being ordered

[@sleeper.simulant7327]

The connecting rods are literally 3x thicker on the FA24 then the FA20, and the crank is beefier. It can handle that torque

[@lowery02]

Man o man. Sounds fantastic

[@cstorey987]

Why this isn't still a from the factory trademark of WRXs perplexes me. The rumble is worth whatever side effect it is a necessary trait to driving a Subaru. Boy am I glad my stock 2008 wrx came with unequal lengths from the factory. Throw in a catless downpipe, $200 3'' pipe with a cherry bomb at your local small town exhaust shop, and you have one hell of an exhaust note.

[@SaxmanUSMC]

Because it is inefficient and causes issues, and totally defeats the purpose of twin-scroll turbo setups.

[@cstorey987]

Yes, but no rumble :(

[@sleeper.simulant7327]

On e85*** which is not available everywhere. This header won’t make past 350 whp on 93... I’m looking forward to my local tuner (VEMS) doing actual tests with these, as it will be unbiased… this manifold will not outperform the stock header, at all… let’s see actual dyno overlays of both cars tuned to the max, let’s see what happens… UEL’s are a ricer mod, pure and simple. You can put UEL’s on a D series Honda, sounds the same as the “boxer” rumble…

[@WLDWRX]

@JDMuscle USA any chance of making a twin scroll unequal length header? I think that would be cool, or make a hybrin header where around town it's unequal length but in high revs it smooths out to equal length so you have best of both worlds with power and performance.

[@peeposadboy]

That’s not possible. Lmfao. The flange still has the same twin scroll flange like on the Turbo. Hence why even on EJ’s if you’re upgrading turbo’s and decide to go with a twin scroll, you need to get an equal length header to support it. Just because it’s UEL doesn’t mean that 2nd scroll on the Turbo isn’t doing anything, exhaust gasses still pass through. Lmao. When they say these UEL Headers turn it into a “single scroll” they don’t mean literally. Because of the unequal exhaust pulses it essentially just acts similarly to how a single scroll turbo would, but still not as laggy. Hence the 300-400 rpm lag in boost.

[@joshstane5926]

When can i get one, is the real question?

[@716Flat4]

could the results have something to do with not only the extra displacement, but the smaller boost and lower compression? The honest truth is, the twin scroll really woke up the low end power on these...but they made em sound like hondas. I think if you want to take the 2.4 back to unequal, the best thing to do is probably drop the TS and go with a more classic turbo. I am betting you can push close to 20lbs of boost on these but what do i know, i just watch all these awesome channels spend money on shit i cant afford to have lol.

[@basketball1591]

Thought unequal length headers causes the car to run with less power and eventually leading to a blown engine

Wasn't, they made a single scroll headers for a dual scroll turbo. Could be the issue they are running into with loss of power in the low end. A dual scroll headers uel or EL will more than likely out preform the current design in the video. Granted I give them prompts for testing and trying. Header design is honestly science.
