[@JordanManfrey]

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 Oh huh, I had no idea crossplane cranks were even a thing. Ya learn something new every day.

[@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. Since this custom header has 4 different pipes all different lengths we now have a custom UEL (unequal length header) which gives that rumble noise. Look up civics with 1320 UEL header for more. Sounds really good!

​@@louismoench3554Satan is that you? 😂

[@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.

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.

You are the saving grace of my inline 4 questions

[@JustBeingHonest813]

Damn... That actually sounds REALLY good!

[@ninjanix7288]

Love the inside sound🔥🔥🔥

[@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.

[@geren11]

what I like most about this is that you can see the firing order of the cylinders as it starts up

[@arturkoriakin1766]

man this is amazing👌I loved your 2 way stuff but this takes it to another level!! + you can see which cylinders are behaving😅👍 Make a 6 cylinder one!:)))

[@BersekViking]

Love the sound!

[@danelhouseofel7634]

If you put a muffler for each exhaust, imagine how mich better it'll sound! I actually have been wanting to see someone do this exact build. Thanks for the upload.

[@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.😅

[@kylepark5292]

this sounds absolutely incredible, and very inspiring to people who feel ashamed of their straight 4 engines, definitely wanna do this to my own car!!

[@repingers9777]

Ive notice the crappier and older a 4 cylinder is it has a "better" sound like similar to this one in the video 😂 i think the rasp and higher pitch comes with performance advance timing equal headers and high rpm with bad exhuast isnt too pleasant but it can be its just rare lol

When I joined the Navy in 2003 and got stationed in San Diego I had to buy a new car to share with the (now ex-)wife as my POS 1987 Bronco II with blown head gaskets was never going to pass CA inspection and we bought a 2004 Nissan Sentra SER Spec-V and this video gave me crazy flash backs to beating the piss out of that car.

[@basedemt6608]

F**king love it. I can tell how loud it actually was and that is downright hilarious.

[@BornToSneeze]

0:43 You just reminded me of the time I found my vise grips holding my exhaust on when getting rid of my trusty old Focus wagon. It was supposed to be temporary to get me home from when it got damaged (pothole) but worked so well I forgot. It had passed 3 inspections with them on, lol. Says a lot about MVIs in Canada.

[@somedumbwitch]

never heard of this channel before, and frankly not even sure why KZbin recommended it to me, but subscribed instantly upon hearing "you either is or you ain't"

Can't really understand how loud it is through the video until I see you wearing earplugs in car. The sound though really pure and raw...

Im impressed. It sounds pretty good.

This is the best I've heard a 4 cylinder sound

[@musotica]

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!

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.

[@palikkalapsi345]

Im pretty sure Top Fuel drag racing cars arent very technically advanced. The reason theyre the fastest cars in the world is the fuel they use which is 90% nitromethanol.

[@Bangmomsmakebombs]

@@sidefx996although not fully informed, he’s not technically wrong. Sure the fuel is nitromethane and not nitromethanol but the tech in those cars is not cutting edge by any means. It’s just built up to withstand the abuse thrown at it, but most of the parts are based off production parts

[@duncanbeard9460]

Zoomies work well on any engines with large superchargers, using collectors & other items to improve scavenging is of no benefit. I have a blown methanol car, see my chanel for a few onboard vids - fastest run so far was 2 years ago, 7.50 seconds @ nearly 180mph. I'm just learning to drive it having learned to tune it & its huge fun.
