Exhaust- / Sound Discussion

I can imagine. If you dont mind me asking, what were you looking at £-wise?

Track Day ~£120-£160 depends where
Insurance Mine was £230 for the DAY - Also insured the excess of £1500
On track you are responsible for damage to your car however and whoever caused by!

Fuel - Approx 10 MPG on track

Used to take my Skoda Octavia insurance was about £100 less, but cars value was less than half.

For an occasional go / learn / experience your car it has to be done.

Its my only and daily car I cannot afford to not insure it, did have a little accident with a Ginnetta once on track - repair was 3.5k!!!! Insurance covered it - NOT my fault.

I got my best ever pops today.

2nd gear, very cold morning ~1C up hill, floored it to flashing lights upshift time.

Got 2 good pops, then a pause, then another pop!

Yes I wind my back window down at the start of this hill, yes I giggle like a small child when it pops. Yes I am old ish with my own kids :p

Yes I will do it again tomorrow, and the day after that, and the day.....
 
Mine sounds quite random and I love that. One of the last cars without the gpf. I think the inconsistenty makes it sound very natural. I get burbles releasing from 3k rpm but only right after accelerating a bit so there is fuel to make the noises.
On the nordschleife the noise was even louder and I could feel the bangs through the seat also at the end of 4th gear.

I feel like mine is pretty poppy but its not consistent. I've read people say that its so artificial that its the same three pops on every shift but I don't hear that with mine.
 
Right, firstly I apologise in advance for another post confirming that my car pops and bangs regularly but it’ll be my last word on the matter!

Further to what I have said previously, if I do a rapid press of the throttle and up shift from 2nd to 3rd for example, I get one bang usually. So revs are under 3k, or just a little higher.

I am starting to realise that the exhaust noise is really not that predictable (thought that was an unfair criticism that one or two reviewers said), and actually, there’s loads of different scenarios where you hear pops and bangs.

That’s me done with this thread:eek:
 
@MeisterPanse if you want to upload a video do it through youtube, or at least not as an upload on some dodgy website like that, I got a crapload of warnings. Consider yourself very warned.

Absolut no warning error @ my PC here in the office with chrome. I don´t consider. 5 Downloads have been made. My God........ Here on another platform. http://sendvid.com/qh88vczw

The Crackling is getting louder every 500 km. while driving its present over 3000 RPMs.

@N-Raged; My most reliable pop initiator, and easy to replicate, is to, when the engine is hot, go to 4500 rpm in 2nd gear and then back off. Three bangs, back up to 4500 rpm and back off, three bangs, repeat. No need to change gear or touch the clutch. HTH.

Thanks for that, but that doesn’t work either, all I can say is that Hyundai know about my issue and the N performance team are looking at a solution for it..
 
Pops and bangs are good and bring a smile to my face however the corresponding speeds involved can be risky for my licence on public roads.
What I am into at the moment is driving through the side streets in N-custom (Exhaust set to sport +) and just driving normally with the window down. The gurgles, rumbles and burbles coming from the exhaust just shifting up and down at legal speeds makes me smile and is not a licence risking activity.
So it seems the small things amuse me as much as the "hair on fire" things do too. I still have no idea if the sound generator is working or not. I guess from Hyundai's perspective this is a good thing and they have done a good job with the artificial sounds if it is working normally. If it is not working then I seem not to need it as the noises I hear from the car are more than enough to amuse me at this point it time anyway.
For reference - Car is only 6 weeks old and 2250km. I am running on 95RON :cool::)
 
As far as I understand (based on different videos), GPF cars have 91 dB exhaust volume and older non-GPF cars have 109 dB - that's quite big difference, I'd say... older cars seem to be more crackling and burbling

 
I testdrove both. The 109 and the 91DB Car. But there was six month between so I couldn´t hear the Cars next to each other. But I think I liked the crackling on the 91 better. It sounded less digital for me, more real. It definitly sounded great!
 
As volume doubles every 10 dB that would make the old car more than three times as loud as the GPF equipped one, doesn't seem credible.

I thought the GPF cars were only for Europe due to the there emissions standards, I don’t think the Aussie cars got fitted with them? I think it’s something to do with the fuel down here as well, I read an article about VW who are struggling getting cars to Oz because our fuel isn’t compatible with these GPFs, so there cutting down the model variants, so if they can’t do it then I guess Hyundai can’t as well?

WOW. The misinformation in this thread, or even better lack of information, is outstanding.
Do you even know what the 91dbB and 109dB values stand for?

It is the intensity of the exhaust sound of a vehicle which is stationary, a vehicle which is not moving. It is measured at 3750 RPM. And that's the 109dB value for MY18 and 91dB for MY19 respectively .

MY18:

MY19:

The driving/road noise of the car, is 72dB for MY18 and 71dB for MY19.

And no, 1dB difference is very hard for the human ear to detect, even for professionals in the music business.

Also, the human audio memory is so incredibly short, that there's no way someone will even notice the difference between the two cars while driving.

As of now there is zero evidence that supports that there is any difference between MY18 and MY19.

There is also a huge number or variables that make such comparisons futile. (fuel, air pressure, engine state, speed, RPM, human input/error, temperature, etc).

If yours doesn't correspond to the norm, then it has to do with your specific vehicle and not with a production year as a whole, and you should probably look into that.

Like @speedking said.
so how you can describe such a big difference between standing noise?
I'm not a Hyundai engineer and don't know how or why and I'm not going to guesstimate. The only difference you may notice while stationary with the MY19 is that the sound is not so aggressive till ~4000 RPM. To be honest I do not care, because I don't sit in my driveway revving up the engine.
