True Dual Exhaust on a 4 Cylinder - What Will it Sound Like?
HTML-код
- Опубликовано: 24 апр 2023
- Here's what I believe to be the first true dual exhaust video on RUclips. I put a true dual exhaust system on my 2002 Nissan Sentra SE-R Spec V to hear what it sounds like.
4 cylinder car engines always sound the same to me no matter what, and I've had the idea for a dual exhaust cooking in my head for a while.
I made a video changing the header pairing for the people wondering about that ruclips.net/video/rEDtQp8po84/видео.html

Lmao wtf. Literally was thinking about pairing as I’m watching this. Nice!
OK FELLA... You THINK you're smart... 😛 WHAT ABOUT 3 into 1 AND a 1 into 1 exhaust system? (2 pipes, 1 handling 3 of the cylinders, the other handling JUSt ONE cylinder)... HOW wil THAT sound eh? 🤔😏😉👍
😎🇬🇧
Make a kit.
Make a kit!!!!
Is the kit ready yet??
😂😂😂😂
Great video
This has to be the longes fart I've ever heard...
After your mom's.
Nothing beats various V8s but this sounds roughly 7324 times better than any farting four I’ve ever heard.
Previous best was Subaru boxer but this beats that.
(Plus boxers are SO weak like, vroommm SNAP… repair repair… vroom vrooommmm SNAP… repair repair… vroooSNAP… goes in bin🤓)
Bro singlehandedly solved the longstanding "shit box" sound in 3 minutes.
Facts lol
3 minutes plus shipping
I mean it still sounds like a shit box lol
It's like if a moped and a bike had a baby.
🧢🧢@@LT3D
It sounds like a well mixed cross between a Subaru and a bike engine...almost reminiscent of a Group B car. You've unlocked a new setup for 4 bangers that doesn't sound shit.
im now processing how you could make a decently quiet true dual for performance on a sleeper. would sound good and hopefully close to stock with the smaller pipes needed.
lmao it does sound exactly like a bike engine, probably because of how only half the cylinders going through each pipe gives a pulsed characteristic to the sound.
Four cylinders are boring as heck, any UEL setup that isn’t completely straight pipe is gonna sound good unless it’s a tricked out 4ag which sounds good even firing
No this sounds like shit for sure lol
@@bmthfan1231 says the bmth fan (jk)
The fact you made this a less than 3 minute video and got strait to the point makes me wish everyone was like you. You earned a sub todau
I like that too. RUclips has gone to shit in recent years. Every car video is some half an hour long vlog consisting of - absolute highlight of the video shown in the "intro". Then it's another introduction. Followed by 3 minutes of advertisement of some VPN solution some useless product. Then its 10 minutes of random footage. 2 minutes of actual themed video and then again random bullshit for 10 minutes. (90% of screentime is someone's face in "selfie" format)
I don't really like short form videos.
@@Mart77 In todays video: (best scenes). I hate this trend, I clicked on the video because I want to watch it as a whole thing. Learned to fastly skip this part, because its just spoiler..
I was at the autocross when you ran that car. I think you put on the best show that day!
Yeah that was fun. it's twitchy and loose, the rear end comes out easily to spite being a fwd.
A little bit Subaru, a little bit Honda magna... neat.
Didnt mitsubishi make the magna?
@@stanb1455 motorcycle, not car.
Yeah pretty accurate actually
Yooo y this comment make me lol 😂
Yo I have have both and let me say, yes. Yes indeed 😂
Well dang now I'm super curious what difference an x-pipe would make. It does sound deep, unique and different. I like it.
X pipe video is coming at some point.
It will sound like any other 4 cylinder again...
@@identiticrisis no it wont... you dont know anything about exhausts do you
@@sigmamale4147 Ha, I guess not! Good job hater's garage actually did the hard work so we internet debaters have the hard facts instead of relying on baseless assumptions and emotional arguments that only serve to soothe egos.
@@identiticrisis whatever dude... ive heard enough x piped engines to know they sound very different
You take that first comment back!
-Every Subaru ever.
Subarus are the only non-4 cylinder 4 cylinder
Subarus sound the way they do because they usually have unequal-length headers. You can make an inline 4 sound like that if you go out of your way to mismatch the header lengths. Unfortunately it also isn't the best for performance--you gotta choose between sounding cool and going fast(ish).
I was concerned about my exhaust noise , and was about to give up cars but now youve given me hope for the future 👍
I'll be adding an X pipe to see what difference that makes soon, stay tuned.
cant wait
Cool! I'm curious are the header runners totally equal length? My factory mr18 has only slightly uel runners and it does add some rumble
@@spsproductions2614 I'm actually not sure if they're completely equal length. I doubt it would make a big difference in the scenario though.
@@HatersGarage Got it👌
Cant get any worse !
Dude... that may be the best 4 cylinder exhaust i have EVER heard
Check out the old Alfa Romeo V4 engines, very similar sound, very cool.
SRT-4
Almost any WRC car 1990-2010.
I'm happy that you read the article that said don't do it and it made you want to do it! That sounds great! Your car sounds awesome!
this came up on my recommended and i really like this video style!! great video 🙏🏼
Without a doubt one of the coolest sounding 4 cylinders I've heard. Down low you get a Subaru sort of rumble and up high it sounds like a v4 Honda magna which is one of my all time favorite sounding bikes
SRT-4 hands down has the most aggressive sound hands down
Awesome video, straight to the point. I like it. Sounds nice, almost like a boxer engine.
It does sound like a boxer!
I have 2 of the same car as him. One has an unequal length header and sounds like a boxer, just not as pronounced. But very cool video overall.
Boxers only get that sound from UnEqualLength Headers (often called UEL headers) which is somewhat similar to this (I know there's differences...)
@@experimental0000 Yeah. There are Subis without the uel headers and they dont sound subaru at all.
Porsches are boxer too and sound completely different, or the old vw vans, beetle etc
Boxer 4's like the typical subi rumble get the sound from unequal length headers not because they are boxer engines.
Straight to the point video. I wondered, I welded and I wrecked havoc on my surroundings. Love it
OMG. I really thought for the last couple of months about this exact idea! I love subarus and know of the unequal headers sound, and how on some 6 cyl inlines people put 3/3 exhaust headers and thought to myself if with that knowledge I could make my new winter shitbox in the face of an Audi 80 B3 with 1.8 4 banger sound interesting. And here I am getting your video recommended! Thanks for the video, genuinely! 1 left left to know if it's going to sound even better with an X pipe or not. Respect man!
This is the best sounding inline 4 ever Holy shit i want a S2000 with true duals
To be "that guy", the F2.2 much prefers a 4-1. Part of the reason even race exhausts don't do this is because you lose scavenging. Honda usually puts really good exhaust on their cars from factory or they used to back where they were good...😊
I did this three years ago with a friend!! We took a 1991 legacy and did a true divorced dual. With 2.5" pipes it sounded just like a V8
Yo, what muffler did you use? Do you have a video ?
@@vakarispargauskas5422 No mufflers just 1.75" straight pipe per side to 1.75" in/out no name resonators, to 2.5" per side. Had videos on my old RUclips which I lost when I deleted my Google account :(

@@livingthelife8443 well not everything you can go with that thinking eah....the money you save on exhaust you can spend on the stuff that matters, I just find that people are robbing themselves on these thousand-dollar exhaust
Yeah dual exhaust always sounds nice! This was my expectations, at least so far as getting it to run correctly anyhow. Cool vid!
Nice. I used to have a 2002 SE-R spec V from 2003 to 2008. It was such a fun tossible car. That sound from the true dual exhaust is excellent.
This actually sounds really pleasant
I’m in love with the guy that made this video
Impossible as this is the Haters Garage....
Y'all should kiss
Love it! Extremely unique. Great job and thank you for doing something I’ve always wondered and never dared do 🤣
That sounds good
Probably the best four-cylinder I’ve heard
Lol so sad
ive got a 2017 toyota 86, modified exhaust. it has a sound like ive never heard before. i bought it as is and im in love with it. whoever owned it before me... props to you man, its beautiful
you have boxer engine, thats different type of engine
Still a 4 cylinder tho@@DaysDH
@@gymusen and fa20's still sound like shit....lol ..... Best sounding 4 cylinders are the 4age, bmw m10, bmw m12/F3, Alfa twin cams, and DTM spec bmw e30 M3s/cosworth190es..........
I like those cars, very Miata - esq
Would be interesting how the sound changes depending on which cylinders you pair up... 🤔
Done ruclips.net/video/rEDtQp8po84/видео.html
Subject to correction but exhausts work on pulse and you got to match the corresponding cylinders together for a balanced motor...if not you could end up with blow back into the cylinders which kills power of the engine...i think its mostly 1st with 4th and 2nd with 3rd banked together...depends how your engine is timed
I love the “ identifies as a blue door” 😂
This sounds really good as is. For a car of that kind, made with simple tools and materials: is freaking AMAZING!
When I was a kid my dad had a 81 Dodge D50. His buddy that owned a muffler shop built him a set of headers and ran duals with 12" glasspacks out the back. It was ridiculously loud, but I loved it.
When I started buying and wrenching on cars in my teens, I bought a 1980 Suburu Wagon and gave it the true dual glasspack treatment. That thing was a blast rowing through the gears.
My first car was also a 86 Subaru gl wagon but with the exhaust chopped off at the headers 🤣 (edit) with the 5 speed as well sounded so amazing shifting gears the deceleration sound in between lazy shifts and those old engines didn't seem to have a Rev limiter 😮

RUclips isn't really a fair platform, most of all the car channels you see that are big have teams behind them and are working with people who work inside at RUclips. Look up some of the top RUclipsrs and many of them work for the same talent agency...
Dude that sounds so sick I love it
U turned it into the sound of dual cylinder wich i congratulate ur effort ..theory says so also thnx man
Your selfless contribution to humanity, in your quest to answer the big questions has left us eternally indebted to you sir, thankyou for your service.. 😆👍.
Fascinating way to get something similar to a Subaru without doing a unequal length headers, definitely going to see if it's possible with my car because UEL headers would have been more of a challenge than this style.
I think the true dual setup out Subaru's the Subaru UEL sound.
@@HatersGarage Definitily, gives it a sound closer to a 270 degree twin cylinder motorcycle
Sounds sweet mate. Nice work.
Had an '88 Olds with a quad 4, and no catalytic converter. It actually didnt sound bad. The converters were burned out. Your car sounds really good! Impressive! Love the ending!
I need this for my 04 altima so bad. I just got the dual exhaust rear bumper from the 3.5SE and I’m just now figuring out my exhaust. Thank you for this. You have found the perfect sound.
Do it! Nearly the same engine that's in this video too, funnily enough. The QR sounds great for a 4cyl to start, when not connected to a CVT that is lol
(I know the Altima didn't have that for 04)
If you just picked up the merged pipes off the stock manifold, you likely have 360° firing pairs in each pipe. It sounds a little lumpier because they're unequal length between the individual cylinders, and the spacing between the outlets doesn't even those out at all (like an x-pipe would...)
The 360 pairing is like Honda's F2 engines from the 1960s and the S800 racer, both had "true dual" exhausts and clips can be found on RUclips.
Pairing the cylinders differently at the manifold / head would yield something closer to a boxer 4 sound, or indeed Honda 4 cylinder motorcyles of the '60s and '70s :)
It really sounds fantastic, what a throaty sound from a 4 cyl, super neat that it sounds a bit like a bike mixed with a subaru
Hey... nice Senturabu 😂👌 worthy viewing material, nice sense of humour/editing on display.
Finally someone did that! I was thinking to do that, but i dont know welding.
Would be nice if you had include a comparison of sound difference before and after
I think you have just earned a sub.... continue doing stuff like this please
33 seconds in its already a great video
That actually sounds way better. A true dual vtech would sound insane.
I want to do one with 4 individual exhausts that run all the way to the back.
Now that's an idea :)
That genuinely sounds really good
Okay, I like that sound. Definitely an improvement.
I'm impressed, you made that Sentra sound good! Now you need to sell it to all other non-flat, 4 cylinder powered cars and get rid of the failed sneak-fart sounds on the street. You know what I mean, when you need to fart really bad and feel it backing up like your stomach is going to explode but you are with people you don't want to hear it, so you lift and squirm a bit to see if you can slowly and carefully release it and somehow it all goes terribly wrong and you sound like a Honda... Yeah, that sound. :)
I have been wanting to do this for a few years. My idea is more towards a twin turbo setup though
lovely video, sounds great!
Out of curiosity, what cylinders did you pair with each other? 1&2 in one pipe 3&4 in another, 1&3 / 4&2, 1&4 / 3&2? All these different combos could make very different sounds when compared, i want to know what you chose to do.
And also would need to know the firing order.
It was paired 1-2, 3-4. I just changed the pairing to 1-4, 2-3 for even pulses, that video should be out soon.
@@HatersGarage sick! I've been glued to my phone waiting for new videos from you. Keep up the good work bro.
If you want deeper sound prolly do the cylinders that fire right after the one before it

This sounds actually awesome
Dang, I'm not a 4 cylinder fan but, It sounds pretty good for a 4 banger. Nice job on your quest.
Sweet! I've been toying this idea in my head for a long time. When making a "true dual" manifold for a single bank engine did you have any troubles with the upstream oxygen sensor properly reading the engine? With a 4-1 or 4-2-1 manifold the o2 is in the collector reading all of the cylinders exhaust and reading it but in a "true dual" setup you'd only be able to read 2 cylinders with the o2 (unless wiring up another o2 for the other 2 cylinders although I'm not sure if that's possible without stock ECU without mixing up the readings). I know like me this was more of letting the intrusive thoughts win type of deal haha but do you know which cylinders are preferred to have the o2s read or it doesn't really matter? I want to do this to my 4 cylinder but I wanted to research exhaust scavenging to get the best performance out of it when making the exhaust runners and take it a step further by creating 2 manifolds to see the differences in sound and power if any. My engine firing order is 1-3-4-2 so I wanted to make one manifold have 1-3 on one side and 4-2 be connected on the other so its two pulses on one exhaust pipe before switching then the other manifold could be 1-4 3-2 so there's one pulse on one pipe then goes to the other pipe one pulse and then goes back etc. Just trying to help make some sound that isn't a fart can :)
The o2 sensor on my headers was already sort of only on two cylinders to begin with. It's up way before the 2-1 collector and could only really read two cylinders anyway. The car runs fine, and there's no check engine light to do with an o2 sensor. My firing order is also 1-3-4-2, and my cylinders are split 1-2, 3-4. Having headers setup to have 1-3 and 4-2 paired would probably sound more "normal". As for flow unfortunately a dual exhaust is just never going to flow as well as a 4-2-1 setup will. An x-pipe may help flow, but will mostly remove the "choppy" sound as well as increase pitch. If you were to install headers with a 1-4, 2,3 split with an x pipe, I'm guessing it would sound like a regular single exhaust.
You can usually just do any of the primaries and its fine, some hondas already used 2 upstream o2 sensors for tuning as early as 1987 on the JDM b16a.
There are 3 ways to make a dual-exhaust four-cylinder:
1) pair cyls.1 & 2, then 3 & 4.
2) pair cyls.1 & 3, then 2 & 4.
1) pair cyls.1 & 4, then 2 & 3.
Each of the above, sounds rather different.
Which option did you use in this vid?
i think the easyest so 12 34
I made a video on header pairing ruclips.net/video/rEDtQp8po84/видео.html
I’ve heard V8s that sound like that so I think it turned out well, nice work
This sounds really good, almost like a V4! The motorbike analogy seems to be accurate though.
Not all 4 pots sound the same. Old school (not 90's, but like 50-70's) rally car had some cool sounding 4 cylinders. Also the Cobalt SS and Dodge Neon Srt had some deeper growls.
Equal (honda) vs Unequal (subaru) length headers have a big differince as well as 4-1 vs 4-2-1, and chambered (deep) vs straight through (raspy) mufflers.
I really like the rumbling sound of true dual, it reminds me of the V8ish sound you get on old Inline 6s with true dual headers, with X and H pipe this just goes ricey.
I'm tempted to have an exhaust like that but on flat plane 4 cylinders firing in pairs there would be a huge mess with the flow so it's going to lose performance for sure, there just isn't anything to pull a vacuum after each pair fires like in a single exhaust which has excellent flow due to each pair's exhaust pulling the other pair's out, not that the pulse from its own exhaust doesn't do it, it just doesn't do it as effectively.
Yeah on any 4 cylinder a true dual exhaust doesn't really make sense from a performance perspective.
@HatersGarage what about on a boxer engine?
It already has two banks.
@@HatersGarage as an exhaust novice looking to mod my q50, what should I tell my local shop to have this sound?
would sound mostly the same.
@@josh97941 Tell them to split the headers into two separate pipes all the way to the back with an h-pipe. (and ignore their suggestions not to do it due to flow and blah blah blah)
It sounds like a beast , love it !!!
That sounds freaking awesome!
The slightly clappy sound could be alleviated by like magnaflows maybe and a resonated tip and x pipe. It helped my m45 which is a v8 nissan basically and them and titans have that cis/ clappy sound and doing what u mentioned above made my car sound great 😊
I find it funny that you use a STI to make the dual tip point, after saying all 4 cylinders sound the same. EJ20/25 have a way different sound with a bigger exhaust, mainly due to headers but its still a different sound when just the exhaust is changed
unequal length headers on the subaru. You can get em for hondas to make em sound the same lol.
HELL YEAH! I love it!!! Thanks for sharing!
man has never heard another 4 cyl outside of honda and says they are all the same 🤣🤣🤣 hilarious vid bud, best of luck in the future.
please try swapping the header collectors onto alternating cylinders to see the sound difference
That could be interesting, I have a feeling it would sound similar though.
@@HatersGarage how did you split your header? Believe it or not, a couple months ago i had the exact same idea, did the same research, found nothing but that exact same forum, and decided to do it to my honda accord. Did the exhaust about a month ago. (Low key pissed that i found this video cause i wanted to be the first to document it but you made a more interesting video than i did so i give you props (as long as you didnt secretly see my video and steal my idea 🤔) I already had a header that was 4-2-1 that i used. Though this header paired cylinder 1-4 and cylinder 2-3. And with that split, each pipe has an even firing split (firing order 1-3-4-2). And i wanted an odd firing split so i cut and reconfigured my header to pair 1-3 and 2-4 for an odd firing split. Guessing based off the sound, that you paired yours 1-2 and 3-4 which also would be an odd firing split. Thus, your car sounds EXACTLY like my accord. However, i think if i had not modified the header and had the even firing split, i dont think it would have the same deep sound. The odd firing split adds a fundamental frequency 2 octaves below the normal 4 cyl firing frequency, but the even firing split would theoretically only be 1 octave below, and would have a totally different sound. But i dont think it would be as cool.
@@tjziegler8823 You're right, mine split on alternating cylinders. The firing order is 1-3-4-2, and my headers are split left and right. That's why it sounds so choppy and deep. I had this idea in my head for a while too, about a year or so, it just took me a while to get around to it.
Man thats actually pretty nice sounding closest subie sound ive heard but was wondering if you felt like it made any extra power or acceleration?
Yes, it definitely pulls harder. The old exhaust was a pea shooter, (1 7/8") so the new one flows much better.
@@HatersGarageWait… this doesn’t HURT power, it HELPS?
@@zeropointstar Compared to stock, yes.

Wouldn’t bother or consider Xpipe since merge and crush exhaust pulses back to sounding like single farty exhaust sound.
you cant deny 4 cylinder boxer engines sound different
@@christopherbradley8771 I'll rephrase what I said, all INLINE 4 cylinder engines sound the same.

02 spec v... my first car haha. Thanks for the nolstalgia! Dam car had pretty good torque for a 4 banger, I truly miss it
To be honest i dont love 4 cylinders but this exhaust barely changes my mind
Definitely a deeper sound than my 1974 Toyota Celica. My Dad and I split the exhaust manifold back in 1985 to see how different it sounded compared to his 1952 Chevy straight Six. They were close but my Celica had a higher pitch. We ran straight pipes to the back wheels then had 18" Cherry Bombs with chrome tips. Kind of like a High Powered Weed Eater. LOL.
Great to see someone doing a True Dual again.
I did this to my 4cylinder, with equal length runner and a center collector for each running side by side and the splitting at the end sounds really good, Borla exhaust for the win
Sounds SICK AF!
Ooohhh, that is *sweet.* Every 4cyl car should have this setup. Holy crap that's a great sound.
I been thinking of doing this for a while now, thanks for doing it so I can save money lol. Would sound good on my 1.6 Vauxhall clone/Aveo5 lol
Man that sounds good.
I put a long tube header, free, with a straight through cherry bomb type muffler, also free, on a N/A 2.3 87 Mustang 5 speed, and it sounded INCREDIBLE! Seriously reminded me if the Bullitt Mustang.
Still slow as molasses.
Nice job, I like it.
When I first heard it, I got chills and... neuron activation. Sounds awesome!
Hey! I did this with my 2005 camry s a whule back irs been my daily driver for years and the only 4 banger that doenst sound like shit, good on you bro i knew someone else would this eventually
1:44 That actually sounds nice! Its subtle, deep sound and crisp. im sure adding a resonator like a dynomax would tone it even more.
it really sounds like a 2-cylinder bike which makes me wonder if there is a 2-2 exhaust for my 4cyl bike, pretty gud video!
Not bad...Nice b13 too. I saw that creeping in the background 😂
This was great 😃 👍 very interesting.
I've got a Hoffman racing midpipe and cobalt backbox on my mx5 and the result is fairly unique sound. My family can tell when I'm arriving home against the backdrop of other cars with loud exhausts bombing it up the hill outside our house 😂
Sounds amazing! 😀
