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).

[@identiticrisis]

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 KZbin. 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 :)

I did that many years ago with my '68 Corolla. Sometime in the 90's. Made two 2-1 headers out of a 4-1. It only sounds different if you're standing to one side of the car mostly hearing two cylinders. I split it so you get every other pulse on one side. (1-3-4-2...1 and 4 on the same pipe.) If you are directly behind the car it sounds pretty normal. Originally with pipes out the side in front of the back tires and 12 inch glass packs I could set off car alarms. That didn't last long, too obnoxious, I went straight out the back with normal mufflers. Much better. It's got a full NOS factory exhaust back on it now.

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.

@@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.

[@HatersGarage]

@@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.

[@observingrogue7652]

Some motorcycles already do this, and you can split a 4 cylinder exhaust system in two, and have them each go out the left and right side, so your ears on the bike hear different firing orders, Stereo sound. A great motorcycle channel, RacerTV, made a video about choosing an engine for your Cafe-Racer project. Splitting the exhaust is one of the tips he gave, for tuning your sound to your preference.

[@bellsouth70]

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 :)

[@HatersGarage]

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.

[@nobodynoone2500]

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.

[@MARIACHITIERRACACHANILLA]

On Low rpm sounds like a v8 1:19

[@wallsmr1840961]

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 😊

[@ZonymaUnltd.]

What a great way to start a video 😂 Also, leave my prelude alone, that thing actually sounds amazing for a 4banger (with Skunk2 exhaust)

[@nthgth]

Ooohhh, that is *sweet.* Every 4cyl car should have this setup. Holy crap that's a great sound.

[@BGL_basslover]

1:17: squatted truck?

[@roadrunnerorange]

Done it with back in 96 with a 1983 ford exp. The exhaust manifold ran 4 pipes, collected into 2, and then one outlet. Cut the outlet off and ran true dual pipes all the way back into glasspacks. Loud, but not terrible.

[@nhooj8882]

I love the motorcycle comparison. My 4 banger has probably a little longer fake dual exhaust than most, and especially after some different mufflers on there its a surprisingly deep tone. Even before the muffler change though there was just something about the low... thump of it that always reminded me of a chopper. Maybe a weird sound to come out of a car, but a better tone than most 4 cyls' "vacuum cleaner" or "fart can" noises.

[@bbcala9719]

Dang, I'm not a 4 cylinder fan but, It sounds pretty good for a 4 banger. Nice job on your quest.

[@rockenrooster]

This was my first car (aftermarket headers only). Sounds great even stock. Best sounding i4 minus turbo subarus.

[@tgw230]

I’ve heard V8s that sound like that so I think it turned out well, nice work

[@tobordabot]

did this with a subaru 1981 4wheel drive way back in the day( 1985)..one pipe and one glass pack for each side of an H style engine.. tips came out just after the back passenger door..could be heard from half mile away and it was distinctive in sound

[@ERIMUSPERFORMANCEUK]

That has no right sounding so good!!!

[@zombiedearth]

I love the melody of a finely tuned shitbox, birds singing on a spring morning can't compare to this engines beautiful serenade of exhaust gases 🙂

[@Petriefied0246]

This sounds really good, almost like a V4! The motorbike analogy seems to be accurate though.

[@dakodablundon2563]

This actually sounds really good, like one comment said got a subaru kinda mix sound in there

[@Nlangkirby135]

One thing to say… mission accomplished… proper dual exhaust on a four cylinder engine.

[@fabssgarage]

Sounds exactly as an inline-2! But sounds better than any other L4! Nice!

[@d.g.grimma9249]

It sounds a lot like a larger-bore version of an early-70's Honda 750 Four I owned back then, that I added a Hooker 4into2 exhaust system to. Ran great, sounded pretty decent, too.

[@colpoii3rkastutem-168]

I wasn’t expecting it to sound good, it did though! I’m sure there’s a number of motors this would sound bad on but this is certainly not one of them👌

[@louayankit2888]

I think it's safe to say this is the best sounding low budget car we've ever heard

[@glenclifton4563]

The Boosted Boiz did it with a twin turbo K24 put into a MR2. It was a shorter dual system and it was twin turbo so the sound was much different. It probably doesn't really count as to what you're talking about but its the only exhaust anywhere near what you were asking about. They do have a big youtube channel. This was about Two or three years ago. I hope rhis helps.

[@deimosphob]

Some megaphones would be insane on this, probably give back some of the power lost but most importantly sound sick asf. Prob needs math to make power but the sound is where its at.

[@nitousinfinitarius1866]

Thus car sounds amazing, great idea brother!

[@flugjung]

Wow, you made a Nissan sound like a European racing car. Brilliant.

Hey... nice Senturabu 😂👌 worthy viewing material, nice sense of humour/editing on display.

[@G.Suzuman]

It Is like having two bicilinder engines ! LOVE IT!

[@kalitoslyme]

33 seconds in its already a great video

[@Costner1995]

Sounds like a cross between a bike and a Subie. I love it.

[@eldave178]

The 22re engine cammed and equipped with a nice exhaust sounds absolutely amazing and doesn't sound like these whoopie cushion cars that people think sound cool.

[@fsae0607]

Wow, sounds pretty good!! I lost it with the hippo clip 😂

[@JDMKIV]

I’m shooketh. Thou hath made a inlinebaru.

[@bmthfan1231]

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.

[@michaelpotts9902]

My 1966 Corvair engine came with dual exhaust and Borla mufflers...sounds great!

[@benzles8492]

You sir, have too much time on your hands. Love it. Do more.

[@tslim250]

4 cylinder made cool in 3 minutes. way to go!

[@DcGuitarkid]

I really liked these sentras, low key. simple and easy!!!

[@confide3734]

Thanks, now I'm convinced to add a true dual exhaust to my 4 cylinder Tiburon

[@CK-mf6du]

That totally reminds me of a volkswagen beetle engine. Very distinct sound, very cool!

[@MnDakota37]

Congrats, you came up with four cylinder boxer sound with UEL headers on an inline 4
