Your car, probably. These cars have performance engines, chips, exhaust etc. If the driver (owner? operator?) thought it was bad for the car, they probably wouldn’t do it. Someone probably has 75k+ sunk into that car. They’re not going to race the engine just to wreck it at a local hot rod show.
Pretty common for some race cars especially ones with short exhausts like Porsche. Follow a 911 into a corner and you get a hell of a shot thrown at you. The tuners blip the engine quickly and the unburned fuel can ignite. But, it’s a oood way to lose your exhaust pipes.

I doubt it’s harmful, but it’s stupid.
Is what bad for your car? All you did was post a link to a video. That’s not an auspicious start to a thread. Use words. We like words and are not afraid of them. You tu(be)?
But if you just click on the link it’s pretty clear what the OP is asking about.
Except most of us have learned NOT to just click on a bare link sent by someone we don’t know. One of the earliest habits to keep your machine safe on the Internet.
Yeah, does someone want to tell me what video is, because I ain’t clicking. For multiple reasons.
Generally, sure. But it’s a [shortened] youtube link. Hovering over it reveals the place you’ll go is the same as the text you see (youtube). About the worst that can happen is it could be loud or NSFW.
Don’t get me wrong, if everything else about the OP were the same but the link went to a site I’d never heard of, contained suspicious syntax and/or sounded unreputible, I wouldn’t blindly click on it either. But, again, it’s a youtube link.
It’s not much different than a post titled “What do you guys think of this ha ha” and a link to XKCD or Twitter or Netflix.
It would be extremely unlikely to have your machine compromised by clicking on it.
And, FWIW, if the OP had added some context that wouldn’t change what happens when you click on the link.
PS, this isn’t directed at you specifically. I know people don’t like OPs with little more than a link, but I’ve never understood the “I’m not clicking on that” mentality when you can see it goes to a site Generally Recognized As Safe.
ETA, @snfaulkner, I didn’t see your post when I typed this.
And, for everyone else that can’t bring themselves to click on a youtube link. It’s someone revving their engine to cause very loud backfiring.
Thanks for the description.
As for not clicking on bare, though generally safe links, it’s more that I’m on my phone and at a place that I cant watch or hear the video at the moment.
I’m brave. NoScript for the win. (aww, ninja’d)
It’s a guy with a Nissan 370Z that’s got flames/pops coming out of his exhaust. It happens because the engine is over-fueling (or worse for the engine, under-fueling) and unburned gasoline is getting into the hot exhaust and combusting.
Harmful to the engine? If you consider the mufflers separate from the engine, sure - it doesn’t harm the engine. But you can certainly damage the mufflers by exploding gasoline in them. I separated the seams in a pair of them when I hadn’t tuned an engine properly.
(Ok, the opinion begins here)
It sure isn’t worth the applause the fools in that crowd give. If the car popped once or twice at a shift when accelerating under load: sure it’s acceptable for a race engine to do that. Popping when revving under no load? Ehh, it’s probably a bad tune. Either way, I can make a Ford 300 cu in six with a single barrel carburetor afterfire reliably. A nice sounding exhaust note isn’t an indicator of power, an afterfire sure isn’t.
It’s not about being safe, it’s just rude. Plus some folks can’t watch videos on their computer at work.
I knew some guy who boasted about a trick that worked in the days before steering locks were part of the ignition system, and before fuel injection. They’d drive down the street and turn off the ignition for a second or two. the momentum of the car (standard transmission) would keep the engine pumping, and suck fuel through - then turn on the engine and it would sound like a bomb going off. Bad news, is doing it one too many times either blew the baffles out of the muffler or split the muffler. Those were the days. He was particularly amused about the time he did it in the Detroit-Windsor tunnel while passing a pedestrian.
Nowadays, I would imagine that regularly causing backfire and flames out the exhaust is not particularly healthy for the muffler or the catalytic converter = but then guys with muscle cars probably don’t care about pollution, unless they live somewhere where cars need emissions testing regularly.
They remind me of the crowd gathering around this car. https://youtu.be/ZwR1-aRTyyM?t=25
Where along the exhaust system does the unburned fuel actually start to burn? Is it in the exhaust manifold? The muffler? The tailpipe? Clearly the visible flame in the video means that the burning isn’t complete by the time the exhaust hits the outside air. Is that because there isn’t enough oxygen in the normal exhaust gases to complete combustion until then?
I think it starts burning at the tailpipe. Essentially, there’s not enough oxygen in the cylinder to burn all the fuel. The unburned fuel gets pushed through the exhaust system (ignoring the catalytic converter - I doubt a track-only car has one) until it finds enough oxygen to explode. That comes when the fuel vents to the atmosphere at the tailpipe. The explosion could come sooner if there were enough air getting into the exhaust system earlier, like through a bad joint in the exhaust system or a weak seam in the muffler. I’d imagine this leads to the occasional exploding muffler or rupturing exhaust pipe.
And unless there’s a trick I don’t know about, there’s no way to “hover over” a link on my phone to see where it goes. (Noted that the URL was visible in this particular OP, but that’s not always the case.)
There’s a workaround. In general, you can long press on the link and hit the ‘copy URL’ button. Then you just need to find somewhere to paste it. Your URL bar (don’t hit enter though) a reply box down at the bottom, Google’s search bar etc.
On a message board, and I can’t speak for Tapatalk, just normal browsing, you can quote the post and you’ll see the URL.
Both methods are more time consuming than most people would like, but as stated earlier, a malicious link won’t become safe just because there’s some context around it.
Unfortunately, at least for now, you have to do a bit of legwork to see where a link points to while on your phone.
I tend to avoid YouTube links because they could be anything from 20 seconds to an hour. I don’t really want to watch a 10-minute video if there’s a single paragraph that can describe what the question is aiming at. I find most videos start with a talking head for a minute or two. besides which, I always have these things muted (at least, to start - who knows what weird noise you get to blare to everyone around you), so a talking head or narration is wasted on me.
sorry for not providing a description, I’m reffering to the flames and loud popping coming from the tailpipes as well as the high RPM of the engine without any load.
