😂😂😂😂

No wonder the Mighty Duster can't bring down the Magnum Opus.

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

​@@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

white smoke means coolant. blueish white means oil being burned off!

Like all the Mitsubishi EVO and Subaru WRX exhausts.

not gonna lie I think that if the car sounds like its going fast there is less chance of you speeding actually speeding if the car is so if you get what I mean (I dont drive yet)

@@gaminggts8644 Nah, people are dumb, but it does work for me. Every time I drive with straight headers, I'm just imagining all the cops in town running around looking for the loud exhaust. (When I started driving, you could get a ticket for Flowmasters.)

A kid on my block ran his truck's 5.7 on open headers for 3 weeks, assumedly until a noise complaint/cops told him to stop. I've also seen a v8 swap civic on opens. A whole lotta noise to get to 40MPH in 20 seconds.

*cough* Honda *cough*

This doesn't sound anything like a V8...

Not sure where you heard v8

​@@keegentilley578 2:55-2:59 I can see where he'd get old school high rpm v8. But then as soon as it's past the camera it sounds like I thought it should

It sounds exactly like the car from Hard Drivin' on the Sega Genesis.

@@GoldenGrenadier Oh hell, I forgot all about that ancient game. Kinda does.

I can see it sounding like a Subaru at idle, not so much revved up though

@@HatersGarage idle and part throttle is where I heard the most similarity. You're right about wot.

it sounds like an n/a subaru ej25. my 00 legacy sounded like this

@@aegixxer1yeah it sounded like a subbi during some parts it was strange it switched from Honda to subaru 😭😂 depending where it was in the rpm range and distance from camera

why so little ? some engines have 100 HP per 1000CC :) without turbo

Put the motor in a go kart.

@@marcelovidal4023Some naturally aspirated engines will make 200hp to the litre tbh. Look at most of the top spec 1000cc motorcycles out there.

I think he was referring to the one specifically in the video, not 4 cylinder engines in general 😊

He probably lost HP due to lack of back pressure. Naturally aspirated engines need back pressure, unless you have a 12:1 (give or take) compression ratio or higher.

That rings so true

I miss old KZfaq too, Back when the motto was "broadcast yourself". It's still my favorite platform, but it's not the same platform it was.

​@HatersGarage me too boys... me too...

It’s still there, you just have to look for it. But since people don’t and only click on what is in their feed, everyone thinks it’s gone.

this comment could be shorter

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.

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

@@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.

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 KZfaq (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.

Found it: BONNEVILLE BOMBSHELL BETTY 2010 on channel 555BROCK. Jeff Brock is the name of the builder and it’s absolutely amazing! Yes it’s an old video but the sound still shivers me timbers.

Most Civics have stock systems with the muffler cut off, so that makes sense

I'ma step up from 1 7/8 inch to 3 inch in 3 stages so I can make trumpet sound from my Civic then I'ma put a funnel coming off 3 inch tip so I can really direct my 3am calls😆🤣

I’m confident you don’t know shit about even engine basics, let alone the science behind why exhaust setups can alter an engines sound output. Stick to gaming. 🪑🤡

Man you must have heard a lot of shitty Hondas. My buddy has one that is turbo and 400whp and it sounds great.

Big ol nissan engine thats why.

As a motorcycle rider I've used this before to know which cylinder is leaking

@@RonaldPlettAs a moped rider, so did I. Was even easier.

@@Mediamarked hah you idiot

@@MediamarkedCould it be Cylinder 1 by any chance?

@@ZaHandle most likely it is cylinder 1

from inside the car is sounds like a 4-71 detroit without the whine of the blower

instead of a crappy 4cyl it sounds like an actually cool engine like an equal length headers on an odd fire v8. this is a big win

Agreed. Sounded great, cept for the probable stupid volume level. I wonder, if you ran the pipes all the way to the rear and put something inline, could it keep that great sound but lower the extreme volume level? I'm guessing the great sound might change in the process but think it worth trying to find out... Not my time or money so I have nothing to lose by asking😃

I am of similar age and have kids. No comment as to who I am more proud of as I watch this glorious abomination.

What does not having kids have to kid with this?

@@roddydykes7053 If you had kids it would less the odds of having the time and money to do such stuff. Doing stuff that few others can do is cool. When falling from an airplane without a parachute , you might as well do some tricks on the way down.

​@@markae0or you could just do it WITH you kids --- even better lol

I'm 63, and while it basically sounds like shit, somehow...I like it! I doubt I'd like it driving past my house every day, but I admire the creativity and willingness to try it. Now, if he ran those for pipes all the way to the back of the car, the added length might mellow it a bit, Then, I'd experiment with different mufflers. I always liked putting the mufflers right on the end of the exhaust pipe.

Right we want to hear the brrrrrrrbpt brrrrr! 😂

Right? "Check out this AWESOME EXHAUST SOUND!!!!" (45 minutes of talking, music playing, more talking. The last two minutes...you start to hear the exhaust and music plays over most of it).

Sound like a prewar car.

Fresh? With this exhaust gases?

I often say that every KZfaq video is at least twice as long as it needs to be, this is an exception!

It does give you a good perspective on how fast the cylinders are firing

I dunno about that... Some quick math for a four stroke engine says: Each cylinder fires 5 times per SECOND at only 600rpm... (50 times per second at 6,000rpm)... ....pretty nuts to think about that, imho. especially if you take it to even higher revs. I chose the 600 and 6k b/c I just woke up and the math was easy... lol 9,000rpm - every valve in the head is opening and closing again at a rate of 75 times a SECOND!!

​@@billymanillithat really puts 17k rpm F1 engines in perspective, jesus

I'm not sure about how obvious it was that the math lines up with the video but what I am sure about is that there are musicians who can easily count 5ths of a beat at 60bpm and that is something i can actually wrap my head around @@billymanilli

@@billymanilliTry tapping five times a second. It’s not that hard. You can see each pulse.

Amen!

This.

Amen. Others do way too much blab blab

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.

all bark, no bite

I noticed that too lol

Oh, THAT'S what that was, haha

😅

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

Mine has been great, I autocross it quite a bit. I'm not a big fan of fwd cars, but I like my spec v.

It’s the shit cars that make this worth doing

I had a 04 Ser had a ballpoint separate and balled it up at over 90mph flipped end over end twice hit a big cement Calvert then smack a pole 25 feet in the air I was awake for all of it and the dang sentry was still idling when it came to rest I kicked the door open and walked away with minor cuts and two fractured vertabrae I miss that car

I had a '91 SE-R. My god that car was fun. The ole SR20 finally spun a rod bearing and I sold it. Wish I hadn't. Miss that car...

reminds me a little of straight-piped 240sx's at some drift days I used to frequent when he revved it out haha. Did sound pretty dang good

Interesting! I know some types of Harleys are well known for having two equal length exhausts which supposedly sound really good as well (better than unequal to some). I'm curious how an equal length 4-in-4 exhaust would sound!

@@vincentkoster6291 I'm curious how a true quad would sound with tuned pipes, i.e. if each pipe were half as heavy as the other (this would maybe cause them to play octaves) or masses ala 1:2/3:1/2:1

​@@louismoench3554Satan is that you? 😂

​@@HatersGaragenot if you cut through your side skirt lmao

How cool!!!

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

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

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.

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.

I think that setup would sound like a Briggs and Stratton go-kart. I have been wanting to do a rear mount turbo video for a while, that's definitely on the bucket list.

wouldn't the second one just be a turbo haphazardly slapped on the exhaust pipe, with some questionable piping to the intake?

@@tiagobelo4965 Honestly, that's what a rear mount turbo setup is. You can make the welds nice, but it's still a turbo hanging on the end of your exhaust.

What about a 3-1 and a quiet muffler on the 4th to try and make it sound like an inline 3 cylinder?

​@@1987FX16 it won't sound like a 3 cylinder. Unless that 3 cylinder is an early Laverda Jota.

Except it sounds nothing like a V-engine 😂

You should hear an old saab v4 with rally exhaust.

@@setoman1 they're referring to an American V8, with a crossplane crank. The difference in firing order makes American V8s rumble a lot more.

I have a BMW Z3 with an inline 6. It's my 'Halferrari'. 😂

@@drakedbz Yeah, I hear them almost 24/7. I wouldn’t call it a rumble. More of a metallic reverb.

Maybe like a cheap sports bike exhaust on each pipe.

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

@@XavierAway out the roof, of course.

@@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.

It may mean your slower, but hey, who wouldn't sacrifice power to make a cool sound

@@lohostege exactly

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

@@LostInPhilly89 I'm dyslexic thankyou

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

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 kzfaq.info/get/bejne/pqyel9CF1JqzlYk.htmlsi=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.
