Sound of the exhaust

I know with my 2020 N, when I put the car in N mode, or N custom with the exhaust in sport +, there is never any pops or bangs when I bring up the rpms and shift. Its a bit louder than the normal mode, but definitely no pops when shifting or revving. I don't know if this is a normal thing for the 2020 model compared to the 2019 model or not.
Are you using N or N Custom?
If you are using N Custom, you may have to put the engine setting in Sport+ as well to get the highest engine logic to allow for the anti-lag. My personal N Custom setting is engine on Sport and exhaust on Sport+ and I get no pops. Go into full N mode which will now bump up the engine to Sport+ I get the pops.

I don't want to steal this post from Vetgamer, but yes, my engine is up to operating temperature, and still no pops. Other folks are mentioning possibly temperature may have something to do with it, as in ambient temperature. I live in central Florida, and so it's been almost consistently over 90 everyday. I don't know if that would have anything to do with retarding the timing on the car or not. If anything, I would think higher ambient temperatures would cause the ecu to retard timing even further to prevent pre-ignition. I always run higher octane fuel anyhow.

This is really interesting. It may just be a difference in the 2020 model (hopefully not). I've driven my 2019 VN PP hard in 95+ degrees and it still cracks and pops very loud at redline. Even when I'm in sports mode or normal mode when the car is warm it overruns and gurgles and crackles at low speeds in 1st gear. The only time you don't hear cracks and pops are as soon as the car starts up. After driving for 2 minutes or so the ECU allows the explosions in the exhaust manifold. One of my favorite things to do is let the clutch in and bring the revs up in tunnels. Maybe this is a problem with the ECU. Have you asked dealer about it yet?

Have you checked to see if exhaust valve is open when in N mode? Just shine a bright light down the right tailpipe to see if the actuator is functioning for the valve. The service manual also has this to add (lol):
• Visually check the valve movement.
Check how the valve moves when pushing the valve inside the tail pipe using a stick.
Replace the rear muffler assembly if the vale does not move.
• Check the valve operation.
Check the valve initialization when starting the engine : check the valve operation sound (click).
Exchange the valve actuator or wiring if the valve does not operate (check the exchange of valve actuator first).

My 2020 pops and bangs just fine in N and N Custom. I even get a nice burble when letting off at lower rpms. The 2020 models are exactly the same as the 2019s in my experience and other N owners I've spoken with at meets. This definitely sounds like either an issue with the valve or with the engine management preventing it for some reason.

I sure appreciate the feed-back, and I will do this "right tailpipe stick/flashlight thing". Thank you.

There are definitely two kinds of sounds -- burbles and pops. In N mode, I get burbles regularly, but "pops" only at high revs (like blowing onto a highway from a stop). In "regular" mode, I get noticeable burbles at the higher revs, but I probably haven't really wound up the tach in regular mode much, either...

If you leave the exhaust setting to Sport+ and engine to Sport+ then you get the pops and bangs. But I have found that if I set the engine to Sport and the exhaust to Sport+ there are pops, but the burbles are there. I'm thinking the engine setting has an effect on the exhaust. The whole reason for the pops and bangs isn't for the pops and bangs. That was not the intent, the whole intent was to retard the timing so the turbo stays spooled up between shifts. The pops and banks are the by product of all this.

Also, fun tip. I'm not sure how this managed to take me 8 months to notice (probably because I haven't had to carry anything too large yet).. but if you have the backseats down, the pops from the exhaust are much more noticeable from the driver's seat. I wouldn't say they are twice as loud or anything crazy, but it's a noticeable difference. Nothing beats having the windows down, but I will probably keep my seats down now as I love hearing the pops just a bit more during everyday driving.

The base does all of that just as much, maybe even more. It sounds a little raspier overall, to me it sounds more free flowing and the PP sounds slightly deeper and more refined. The PP exhaust may even muffle the "snap, crackle, pop" a tiny bit.
Just make sure the engine is in sport+, the exhaust is not adjustable but think of it as always in sport+
On the base the low/mid rpm burble when letting off or shifting is always there, even in eco or normal. I can't remember for sure but I want to say the PP tones this down a little more when in those calmer modes (probably just that half the exhaust is closed so you hear less of it)

Sorry but it can't. It doesn't have the same tune that was specifically designed to make the sharp crackles and pops. And without the active exhaust, it won't annunciate the sound either. We had this discussion a while ago and I believe there are some side by side videos of both, in another thread. If you find that thread, I believe it will provide you with a real time comparison.
