"Create an unequal length (UEL) header that makes any 4-cylinder engine sound like a Subaru. However, at the downpipe, it should transition into an X-pipe, separating the UEL header for cylinders 1 and 3, and 2 and 4, and ending in the X-pipe like a V8. It will sound beautifully like a Subaru Mustang." "I’ll eagerly wait for that video! I’ve already done part of it to my Mitsubishi Lancer, and it sounds like a Subaru."

they should do this with 4 little 2-stage cat/muffler dinguses that can be made cheaply and routed in parallel to 1) sound awesome 2) make failures easier to diagnose 3) be cheaper since its the same small part 4 times instead of 1 bigger bespoke thingy

[@calvinsmith4034]

​@@JordanManfreythe problem with that is the diagnosis of a head gasket failure makes knowing which cylinder kind of unimportant unless there are two banks. That being said you should always do both at the same time anyway. Maybe with injector failure or spark failure it would help but then you would need 4 O2 sensors minimum 8 with a car on each pipe

Wow I think this is the most pure Half V8 sound I've ever heard. 4 cyls usually sound pretty different from V8's despite literally being half of one, but this one straight up sounds like half a V8.

[@Celciusify]

It has to do with the firing order. I4 generally uses flat cranks. "Supercars" like Ferrari and the new Chevy C8 uses these cranks American V8s uses crossplane cranks, the only I4 I know that uses a crossplane is the Yamaha R1.

[@Hell0]

[@Celciusify]

@@Hell0 Firing order and cranks is an interesting subject, 2 cyl bike engines can vary a ton, almost every manufacturer had their own idea on what was best.

[@RustOnWheels]

If you have the space underneath your car, lots of pipe, lots of time and a few screws rattling around in the machine room, you could weld up different lengths of pipe and combine them back together in such a way that the sound actually does resemble half a bank of a cross plane V8. The reason a cross plane V8 sounds the way it does is due to the pressure waves either combining or canceling each other out. You could definitely get half a V8 rumble that way, although in the higher RPM’s it will sound more and more off. Actually, Subaru boxers have a similar sound effect due to different lengths of headers combining, which is why they also have a distinct rumble. I had a Buick L8 which would absolutely sound like a V8 at low RPM’s (but at higher RPM’s the scream would definitely sound very different). There is a crazy Bonneville Buick on KZbin (forgot the name of the car and builder) which is definitely worth checking out; one of the videos of the car is the owner filming it in his driveway for a friend so he could listen it roar. Absolutely amazing stuff. Really makes you appreciate the old Fireballs.

To Everyone saying it sounds like a WRX: The "subie rumble" sound we all know and enjoy exists because subaru boxer engines use unequal length headers.

[@bigbadvoicevo9596]

In the 60's, there is an article about what is called ram tuning. You basically build the pipes to a specific length to allow the exhaust pulse to scavenge out of the cylinder while creating more vacuum for the intake charge to be pulled into the cylinder. There is some math involved to get the correct length figured out, and then you could also add a megaphone to increase the rpm range that the tuning will work with. It does include building an intake to the cylinder to a specific length as well.

[@juanguerrero700]

How cool!!!

[@moneyshifters]

I'd say he understands this considering he openly said that doing this loses power at the start of the video

[@HatersGarage]

If I had lots of money for a dyno I would try this concept vs. a modern system and see how big the difference is

[@identiticrisis]

There's a reason Honda abandoned their individual megaphones in the '60s. But not before they built a 1.5 litre 14000 rpm V12 with 12 exhausts, imagine what that sounded like! By the time they raced it, it was fitted with four 3-into-1 exhausts like everyone else was using. The problem with individual pipes is that they're peaky, even with megaphones. And whilst it's true that they scavenge well at a specific engine speed, they scavenge very poorly at others. They miss out on the inertial scavenging of neighbouring cylinders, too. And there's far fewer options for resonant tuning between cylinders (think the balance pipes on inline 4 bike engines.) They are also much harder to silence. You can get very close in sound with much more sensible packaging and significantly better performance.

[@michaelmoore7975]

In 1958 Doug Thorley patented the best exhaust scavenging, best torque and horsepower increasing headers ever made for V8's. The patented design was a 4 into 2 into 1 concept, called the Tri-Y design. Smooth bends, tuned lengths and diameters to match the cam profile and valve diameters, and engine firing order consideration dictated which 4 went into which 2 went into which 1, is what made them so much better than all others. They can be found in many winning race cars/trucks. Doug passed away in 2021. RIP Doug.

Zoomies have ALWAYS been the most badass exhausts no matter how inefficient or impossible to setup!

[@kevinwilson9589]

When I was in my late teens, I had a new 1973 Pinto with the 1600 cc pushrod engine. I cut a Cherry Bomb muffler in half, took out the guts, and welded it back tocether, then I fabricated a "Y" pipe, and added chrome tips. It sounded a lot like your little Datsun there. Thanks for bringing back that memory for me when life was more fun.😅

[@yourbigfan1777]

Sounds absolutely dope. On low RPM it's like a tank. But the best thing about this exhaust is that on high RPM it sounds like a WRX STI, and the car doesnt even have to have the flat 4 engine!

[@kw2519]

That’s because the thumping sound Subarus are known for us purely due to the two exhaust header pipes being different length. Unequal length or UEL. If you put and equal length header in, it’ll sound like an inline 4. You can actually get an UEL for a Honda D series and sounds like a god damned Subaru 😂 The pipes he made for this car weren’t perfectly even length so they gave different pitches, like a musical instrument.

[@adamharrington25685]

all bark, no bite

[@LegendaryGamingMods]

I bet a little resonator and a high flow muffler (straight through muffler) on each pipe would make this sound super guttural and smooth, and take out some of that loud rasp that hurts ears. I think this has potential honestly.

[@CoffeeonKorriban]

Maybe like a cheap sports bike exhaust on each pipe.

[@XavierAway]

Where would that go? The thing as millimetres from bottoming out as it is…

[@CoffeeonKorriban]

@@XavierAway out the roof, of course.

[@LegendaryGamingMods]

@@XavierAway Exhaust components don't necessarily have to be near the exit. Many resonators are actually right after the converters close to where the transmission is in the front of the car. You could easily put one or both of these further up the line somewhere with a little creative engineering.

[@FiatUno2003]

Ok but why does it sound so good? I wasn't expecting much but this is awesome.

[@G1lgamesj]

Because less (no) restriction generates overall more low tones, same for raspy 3 cylinders. That and really short manifolds also increases the low tones.

i've been thinking about 4-to-4 exits for ages, thinking no one would do it quite like this. now this pops up in my reccomended after it comes out. glad to see someone is brave enough to do it, it doesn't sound nearly as bad as the straight piped single exit dodge dart near me!

Had a lil 960° rotation on black ice, tore the whole muffler system off when I flew off the raised roadbed in my 80's 318i [Germany early 90's)... as I had American plates I didn't bother fixing it. Sounded like that, redline slam shifting, spinning it's tires on all four gears... I didn't even change the oil, 50,000km... left it a smoking wreck when they took me away in cuffs, returning me stateside. You should have seen my daytime ride, an m60a3 main battle TANK ... no muffler either. Accidents are funny... I can still remember the beer flying out of my passenger's can... as if in slow motion, frozen in the air as we spun round and round.

Zoomies are still used in Top Fuel drag racing. They are some of the fastest cars in the world. Zoomies are not used much anymore due to packaging & emission constraints.

Zoomies work well on any engines with large superchargers, using collectors & other items to improve scavenging is of no benefit.

[@mikebell2750]

Exactly what I thought of when I heard it. 👍🏼

[@alterbr33d]

Its the sound of unequal length headers, not the sound of a boxer. The Honda S2000 with these headers sounds like a Subaru that's about to explode or take off kzbin.info/www/bejne/pnfRlaCKpJmCm7csi=d_MLhZ4izIXQ2cZv&t=10 Subaru was pretty much the only automaker to use unequal headers for a four cylinder so people thought it was a sound unique to boxer engines but instead it was just the sound of the headers. Search for what ever other four cylinder with unequal headers they all sound like Subarus which is just the headers.

[@Astrofrank]

I have experienced a 4-cylinder engine with individual exhausts several years ago. The exhausts were made extremely short, as the engine wasn't in a car, and it was super loud.

[@Travelbeatcreations.official]

Holy moly🤩It sounds mental for a puny 4 cylinder, kinda like the WRX, but also not quite so much! I have a suggestion now, are you able to multiply the pulses if you stick with kinda the same setup, but add another Y pipe to each of the headers and 4 more pipes with same unequal length? It would be amazing if you can test it out! If my judgement is on mark, you should be able to double the pulses and make it sound just like a V8😎 I know that this is definitely something I really wanna try with my 4 cylinder VAN😂

[@davekennedy6315]

a `puny 4 cylinder`? Do you know what THE most powerful Formula 1 engine ever made was? It produced around 1400-1500bhp? It had a capacity of 1.5ltr (91ish cubic inches)? It was a BMW engine? It was used in the early to mid 80s? A 4 cyclinder turbo! You even mention an Impreza (certain models over 400bhp in standard trim) theres also Mitsubishi Evos (up to over 400bhp in a standard road car) AMG A45S 421bhp, Ford Sierra Cosworth one of the greatest and most successful road and race cars of all time with a 2.0ltr 16 valve turbo with 200-220bhp standard but 550+bhp in race form! Check out the channel Mk1Keiran to see the performance of a 4 cylinder 2.0ltr 16 valve turbo drag car running a highly tuned hatchback (Calibra Turbo, Cavalier Turbo) engine to achieve the Uks fastest doorslammer time of 7.34 sec quarter! The rest of the world has been developing increasingly efficient and powerful and torquey 4 cyclinder turbo engines that provide at the very least the same power as a US Pig Iron prehistoric pushrod V8 but with a quarter of the capacity!

[@jokerzwild00]

That's kind of their point... It takes a lot of engineering to get those kinds of numbers from a puny 4 cylinder. Whereas a big nasty American V8 just does it like it's nothing, brute force with pure displacement. Further, that person calling a 1.8l puny isn't necessarily knocking it, it's simply a small engine, relatively speaking. Puny ≠ bad.

[@derekallen8060]

The issue with Y pipes is they don't create more pulses like more cylinders do, the pulse before the Y just splits in two. The result is a basically identical sound. That's why you see cars with dual Y tips that sound normal
