[@bobalong131]

I just wanted to say this is the best exhaust comparison I've ever seen of anything. well done

[@djctoafn]

+Dented Yota Totally agree. Still cant decide to stay with my Invidia Unequal or splurge and go equal length though ;-P

[@mjodr]

I agree too! Very well done. Wish others could use this as a template.

[@Aspentera]

literally said the same exact thing lmao. dope video man

[@TechnoL33T]

Right? Straight to the point right after search terms! Thank fuck! I get so tired of hearing some knob talk about his life and daily driver for the first 10 mins of a video of they even get to demonstrating what their title mentions at all.

[@Jxck_adv]

no talking just straight to what we came to see 👍🏼

[@DoctaMarcos]

THIS IS HOW YOU COMPARE PARTS, best comparison video ever.

[@SamnissArandeen]

The performance benefits of equal-length headers can be heard.

[@west1987]

+Samniss Arandeen liked due to Jeb

[@sleeper.simulant7327]

Couldn’t agree more just watching his acceleration part the car seems so much more free revving

[@nthgth]

I mean, he also went from stock to performance aftermarket lol

[@Jradi4Me]

@@nthgth that’s true 😂 😂

[@camerongoll]

honestly the unequal headers sound better to me lol

[@stututututu7722]

Cameron Coll same

[@rileypaterson7117]

Exactly

[@domenicstobie2163]

The unequal length headers defiantly sound better but you go equal length to help with cylinder cooling and overall performance, generally speaking from a daily/street application going equal length is unnecessary for the little bit of power change but In a true high power racing scenario equal length is needed

[@nthgth]

@@domenicstobie2163 thanks for that detail, as I would like to convert my FR-S to UEL for sound alone, but am on the fence because of heat and power. Glad to know it makes little difference if I'm not going for a super race-ready setup, which I'm not

[@domenicstobie2163]

@Bryan Liguori I just did a little bit of research and for the brz and frs platform going uel May lead to a small decrease in power buuut it’s very popular to switch to uel for the rumble and the power loss can easily be corrected with an off the shelf tune from Cobb or even getting a pro tune to get more power but for the most part it shouldn’t be a huge change in power and if heat is something you’re noticing an exhaust heat wrap might be something to think about, at the end of the day just worry about what’s going to make you more excited and happy with your car because there is always ways to prevent and correct the “faults” if that makes any sense

[@SKYLAR7499]

i hate to stay i lovee the unequal length headers, just more deep and beautiful and shit

[@jethzeeltorres9727]

BrokeDudes Garage reading ur comment in my head it sounded like the guy from thatwasepic. lol

[@NeraVantage]

so the equal length headers make it sound like an evo...

[@toddlithgow]

haha

[@smalley008]

+Marco WY i thought the same thing lol

[@CrossWindsPat]

+Marco WY OR basically any 4 banger turbo lol. But it makes more power for sure.

[@ericnalisack9233]

EL headers sounds better than a UEL to me. I hate the broken engine sound from a UEL headers

[@ProVision3187]

equal length headers make it sound like an engine with equal length headers..

[@MTBDojoMTB]

In my opinion the Stock Unequal Length Headers is the "signature" (to say like that) of a Subaru.

[@GreatDrums.]

Seems to pull harder with equal length but loosing that rumble is a blasphemy

[@nthgth]

Agreed, but remember, that was also an upgrade from stock to performance aftermarket headers... Of course it pulls harder

[@Bebopin-69]

Porsches are equal length flat engines

[@daviddoyodance3085]

Bryan Liguori yea I agree, if it was performance unequal like mine, the difference in pulls would be close to none. It most likely would pull the same

[@PatienceGXbox]

But MO POWa BABY

[@naokinakamuratechniquestud226]

Blasphemy 😂 😂 😂 😂 😂

[@MrMrp00pman]

By far one of the best comparison videos I've ever seen

[@sanchoMDB]

This was probably the most well put together comparison video I've seen.

[@MrRobin285]

UEL headders all the way! It just sounds better At least to me :)

[@brianrobinson9979]

I completely agree. You may get more power out of EL headers but it gets rid of the beautiful gargle that is Subaru

[@MrAsdfcool]

Brian Robinson yeah i like the stock more with the boxer rumble;)

[@Individuality1990]

Brian Robinson they sound like wet farts with unequal. that exhaust system sounds like a giant wet fart anyway, terrible system.

[@brianrobinson9979]

Barry Barentsen that response just shows me that you're not a Subaru fan so why would you even bother posting any comments?

[@Jaime7188]

the whole point of a Subaru to me has always been the unequal sound. the equal header just makes it sound like any other 4cyl out there. very first mod I did to my 86 was put the unequal header so I could hear the Subaru rumble

[@BigMoe1290]

Sound quality on this video is so awesome, thanks a lot man!

[@H2PROz]

this has to be the best comparison vid I have ever seen on KZbin Great job!

[@nthgth]

Great comparison video. Just learning about what headers have to do with exhaust sound - I thought the "Subie burble" was mainly because it's a flat-4, but with the equal-lengths it sound a lot like an inline-4. This video is a model for how exhaust sound comparisons should go.

[@Smerdzy]

Or an east-west motor. (Honda)

[@fiatpandaman999]

This has to be the best equal vs none equal vid I have ever watched. Thanks for putting this together!

[@AcidGlow524]

dude I LOVE your editing. Seriously, this is how all comparison videos need to be

[@willnicholas4474]

One of the best exhaust comparisons hands down, thank you and great job!

[@FifthPinned]

great comparison! I like how you split it it up, definitely made it much easier to hear the difference. and from the looks of it, you made some noticeable gains in power.

[@vonerics7711]

Came to leave my thank you's for making a nice comparison vid and was made even more happy by seeing others leaving their appreciation as well. nice vid man, thanks!

[@MZBallistic]

UNEQUAL FOR LIFE SUBIE!!

[@AndyE30]

this manifold comparison actually taught me something new today! fantastic video!

[@jacobsummers2724]

Best comparison video. High quality, good audio, good editing. Perfection. And the car sounds amazing

[@jasontawfik4262]

This video is exactly what I needed, especially the speed run at the end!! Def getting EL headers, not only for the sound but also the performance advantages. I'm running the stock headers with 3" piping all the way down and the low-end rumble shakes everything in the 200m radius when I start it in the morning :/

[@jameswhite5782]

Badass video, I commend you for the forwardness and absent of some dude that like hearing his own voice. Love it need more like it

[@Cynister96]

Best comparison video ever. You're the man, and I'm sticking with UEL. Thanks bro

[@joker927]

High quality comparison videos like this are so rare. Thanks!

[@boulderburwell]

both sound amazing love the volume and tone in cab on the equal length header for sure but i still cant get over that un equal length header sound great video and great quality you sir deserve the like im about to give

[@8thsinracing]

Sounds good both ways, mad props on best exhaust comp video iv"e seen

[@mrbeans2425]

this is the GREATEST comparison video i have ever seen!!!! well done man! Also love the sound .... been thinking about switching over to Equal lenght headers... still has that subi sound but more even. Also just wanted to say ur car is super clean i love it. OTS tune or custom?

[@RubberDuckTrucking]

man that equal sounds good on that pull in the end, the sound of CFM

[@Fistakuffz]

Thank you for this... I've been trying to figure out what its going to sound like for months...

[@Gviper21]

possibly the BEST comparison anyone looking could ever ask for. great sound quality. thanks!

[@glockatory]

I love the rumble but I don't hate the equal lengths as much as thought I would. Someday down the line when my mods get as far as yours I'll probably do the same. Thanks for another good video Ben.

[@andyc7595]

Dont stop making comparison videos you bloody legend!

[@nickkaarslev290]

Best comparison video ive ever seen. Great job!

[@imashankusobad]

Really well done video man! Awesome stuff. Thanks.

[@MontySpecTT]

Awesome comparison vid. This is how all comp videos should be. Thank you for your time.

[@triniboy2007]

VIDEO WAS VERY WELL PUT TOGETHER THANK YOU!!

[@FPSAirsoftMMO]

LIKE everyone else said best comparison ever finally some one shows before and after seconds apart. ITs perfect and a nice sound thing is you need to hear it in person its a lot diffrent

[@KidsTable19]

Best exhaust comparison video I've seen/heard.

[@MichaelJupi]

Best exhaust comparison video I found

[@Xmvw2X]

Nicely done video. This is rare to see direct comparisons for automotive hardware. The debate between equal and unequal length on Subarus is eternal, but this provides a great side by side view of the options. Nicely done. Personal preference: equal length, but I like the smoother sound. Mind you I'm saying this as a guy with a stock unequal length header. I think tuned has a more professional perception to it as do the power gains from better choices(unequal or equal).

[@WrongFromWright]

Really good video dude.

[@madmikemike]

Nice quality well put together video. I dig the EL

[@CrossWindsPat]

Ohhh but the equal length sounds wayyy better when you are gunning it under load!

[@daviddoyodance3085]

ap2pat yea true but it also is a stock unequal, if it was a performance unequal that was catless , it would sound wayy betters like my unequals sound nothing like that cause I have a performance one. And if sounds amazing when pulling

[@Hoodean]

interesting. totally like the unequals better, as it emphasizes the uniqueness of the boxer motor, but the editing of the comparisons is really really great, bravo for a good comparison video

[@mzwandilenzimande4621]

What a lovely Straight forward informative video. Thanks, Subscribed.

[@slammedcorporation3000]

Hand down one of the best comparisons

[@SqubaSquid]

I have a 2011 STI sedan with a downpipe and single exit catback exhaust and my Subie it’s kinda loud. I’ll always run UEL because of the sound. That Subie rumble is second to none. I love to hear my car from the outside because when you’re always driving it, you get the internal sound. Once you hear your car from the outside, it is the best thing ever.

[@ElSikario100]

Best header comparison vid on KZbin imo.

[@Drektek]

Awesome vid showing the comparison

[@lechocolatemoose]

thanks, this is a great rapid-fire comparison. am considering the Invidia Race ELH upgrade from stock.

[@garyscoop]

thanks for editing how you did cause i wanted to hear it again and was about to restart it. haha [8]

[@MDolente4]

Great video. You thought of everything editing wise. Really helpful. Thank you. Did you retune after mounting the EL headers? And was there a noticeable boost in power?

[@toreyweaver9708]

great video. and wonderful comparison

[@andrewpaintball246]

very nice video the best one i have seen by far. exactly what i was looking for. i have the Ti-C turbo back catless on my 06 wrx and was looking a buying some headers for my next mod. i am sold on the Invidia Equal Length Race Header now. i see that you have the Invidia Catless Downpipe. I am running the Greddy down pipe i hope the sound quality will be the same as yours. Very nice video.

[@COSmolinkintov]

The EL sounds awesome during the pull.

[@jonathanwilleford6808]

Great video man!!!

[@Geoff08STi]

amazing sound comparison!!! great video

[@ThePrimebeef]

this is very well done, best i've seen !

[@hcchan1220]

Great job on the comparison

[@tboltsxs]

@Billy Hudson ... you are right its actually the firing order of the cylinders coupled with the way the headers were made that makes the rumble.

[@ReticentIndignation]

I'm impressed, indeed this was a good comparison, very well done.

[@wisico640]

that video, that car, those sounds... music to my ear ❤

[@ltlocus]

the equal length removes the subaru sound and makes it sound like a Silvia. nothing wrong with that but the subaru sound is unique and should be preserved for everyones enjoyment.

[@kg2mb1]

+ltlocus Sounds just like my old air cooled volkswagen beetle.. all these flat engines sound that way,but i think the old beetle sounded better with a aftermarket 4n1 system.This things just another foreign car with a fart can.

[@RWoody1995]

Its one of the steps they have to take to improve efficiency to avoid being forced to discontinue the higher end models altogether :(

[@sleeper.simulant7327]

Performance, reliability and efficiency beat sound out in any rational car enthusiasts mind. Which is why fast subies always have EL’s. Plus with EL’s the car runs better and helps lessen the chance of ringland failure

[@vincevangough6003]

Equal length sounds so much better! Unequal makes it sound broken, with a misfire.

[@randomreptar21]

they both sound sick in their own way. love them both.

[@cesarivan7598]

Awesome comparison!

[@MarcAndreOlivier]

inside cabin with the EL sounds sick

[@flummer]

Thats is the new standarts for comparisons videos

[@Thr33.Sid3z]

UEL all day! I just like the boxer rumble. I do like the sound of the EL when opened up tho! Nice Whip bro!

[@DJW411]

Well done with this video. Fantastic

[@Quantum369Mechanic]

good job. thank you. lets see some more before and after vids!!

[@professorlapis8305]

They both sound so good

[@2011WRBWRX]

yeah, nice video comparison. I think I like unequal sound better, but when you were getting on the throttle with the equal length headers it sounded pretty damn good. my only criticism would be I think the dual pipes look best as the rear bumper cover is made for dual pipes, but I know that there are a lot of performance exhausts for the 2008+ models that use a single exhaust for better flow so its definitely understandable. Nice lookin WRX all around though man.

[@bashy85]

That sounds awesome with the EL headers.

[@mengdynasty6034]

Both sound amazing

[@TKTmon]

word dude. that sound is part of what makes subarus so cool.

[@sonytransit]

Great video!!

[@freestyleskyline]

Holy crap I never thought I would say it but those Ividia headers sound amazing

[@kensingtonpride]

Sweet vid. Nice comparo. Personally I rate the unequal but it's good to see something different. All ej's sound the same to me so its refreshing to see a change

[@vveavedesigns]

Great video, good comparison

[@bensiok]

Nice video. The equal length sounds so much smoother, and rawr .

[@YetiShred]

Very good video comparison! Nothing like the unequal length sound, but equal length is definitely worth the extra power

[@ragek23]

great comparison video

[@briangray2869]

Great comparison vid, like others have said. I didn't notice any difference in acceleration in the pulls but you can definitely hear the difference.

[@driftindan]

That el header sounds so crisp and cleannnnnnnn oh mah gawd

[@driftindan]

Have you seen the new nbr challenge sti? Sounds exactly like the one with el headers.

[@AdamPhillipps1]

I wonder what else was done to that car. It sounded fraggin' awesome with everything, especially at the end. Nice video.

[@mrbombastic522]

very nice video man..I like both though it seems to pull harder and more smooth with the ELH

[@pauliswaycool]

Sounds good but I love the look of the quad tips.

[@136Hammer]

Interesting comparison. Well done too.

[@Guenter34]

Unequal headers sounds way better. That's the traditional Subaru sound.

[@sleeper.simulant7327]

Carboncrossroads actually it’s not. UEL’s weren’t introduced until the 90’s, and real WRC cars have never used UEL’s due to there inefficiency. JDM WRX’s and STi’s haven’t had UEL’s since 2003....

[@joseantonio9042]

Driveitsideways 1 their*

[@sleeper.simulant7327]

Jose Antonio grammar nazi

[@Vanderkitten]

ELH FTW! Sounds badass and spools up fast.

[@skylinegtrforever5518]

cant choose both sounds really good

[@KingOfEden12]

Equal length gives me track vibes. Since most boxer engines are running equal length in racing due to their better top end power. Then the subie rumble ones give me street car vibes. Your typical bolt on, tune with some clean wheels kind of build. To each their own but I like how the equal length almost sounds like a k series Honda screaming at 8000rpm down a straight.

[@custom240sx]

nice video i cant wait to get mine, hoping those and a protune over my ots stage 2 map from cobb should give me a decent little bump in power.

[@theguyswithcars1480]

I run some equal length headers on my 1.8t a4 and I can say that the performance difference here is really what happened. And my stock manifold wasn't even that "unequal". Gotta say tho, both my car and this one sound soooo much more aggressive and sporty than they did with the stock pipes

[@aMoldyUsagi]

Nice comparison, very well done. As for the sound, I think I would prefer the stock headers.

[@Rockit181]

Equal length sounds badass in the high RPM

[@NewShockerGuy]

Thank you for this... ALWAYS wondered what it would sound like, since people say you will loose the boxer rumble... Even though performance is better with ELH, I'd never want to loose the boxer rumble... Such an addicting exhaust note!...lol -N

[@DoctaMarcos]

Best comparison video ever. THATS HOW YOU COMPARE
