ECU tune to bring back pops and bangs
#16
Not sure of what you mean here, if the valves were held open all the time that would present the maximum noise...
It also depends on the rear section (muffler), I have the Akra link-pipes and the JCR Valved Silenced Race Exhaust and the cracks and pops are just about perfect.
I always thought that the programmed overrun noise in the 981 were obvious and over-done.

probably easier and less risky w.r.t warranty to play with exhaust ...

I had a crackle and pop tune on one of my other cars, not only was it annoying to have it do that all the time, it also threw a real bad emissions light when traveling downhill for a long time when the engine was still sort of cold...

not surprising given that it was dumping excess fuel into the exhaust system ... I guess the downstream sensors were seeing that in the gasses... basically its a BAD idea all around IMO might as well buy a BMW that pipes a fake soundtrack into the cabin!

On my 981 Cayman S w/ PSE, the pops and bangs were featured prominently on throttle lift. My wife always thought it sounded like the car was being super gassy and needed to fart all the time.
I don't mind it on the track, but somehow the fireworks felt a little juvenile when slowing to a STOP sign in a residential neighborhood.

Agreed. I always find it funny that people freak out about things like the Soundaktor or BMW's fake speaker noise, but they're just fine with fake pops and burbles created by dumping fuel into the exhaust. They're all phony. The only difference is that the phony pops and burbles in the exhaust also get to spoil other people's day with the lovely 'look at me' sounds of brap brapness...

On my 718 Spyder, which now has the Akra link pipes and the Akra rear slip-on with OEM valve control, I have what I believe is the perfect level of cracks and pops (and an ideal overall exhaust tone and sound as well). Nothing fake about it, and I wouldn't change it at all. This didn't exist before I made the Akra exhaust change, so I consider it a welcome bonus that comes with the aftermarket system change.

I don't fully understand the comments around this being fake...it is always fake, or more specifically intentional. As Larry mentioned, this is caused byun-ignited gas combusting in the exhaust system. In speaking with other automotive engineers, this either results from inherent inefficiency in an engine's design or more commonly, intentional design to give us the fun noises In an effort to meet increasingly strict emission standards, Porsche has removed that from the behavior of the engines. More efficient use of gas but fewer fun noises.
People use the term ‘fake’ to disparage the exhaust crackle. Fake would be accurate if it came from a speaker as it has no direct relationship to the exhaust, but in this case it’s real combustion, creating real noises, coming from a real exhaust. A more accurate term is deliberate, intentional, or tuned but thats not negative enough for the narrative. Everyone has different preferences on what they want their car to sound like and thats OK. But the people on here aggressively pushing their personal preference onto others as if its the only correct answer is kind of ridiculous. If the OP likes the pops and crackles and makes him appreciate his car even more, then let him enjoy it.
I think the exhaust noises added character and enjoyment, especially at low-mid RPM range where we do most of our driving, and wished Porsche had been able to keep them on the current generation cars. If I were to look into adding it I wouldn’t try through an ECU tune and I’d look at ways to get them added by the muffler design.

Agreed, engineers go to great lengths to develop the sound profile. All the fun noises a sports car makes are intentional. There are many areas the engineers can tune; pipe diameter and length, header collector packaging, and even ECU tuning. The Lexus LFA is a great example of acoustic engineering, they spent a lot of energy developing the sound profile and one reason why its one of the best sounding cars ever made. There is a lot of great information about the acoustic design for this car, its very interesting stuff to read.

Nonsense. Engineering the firing order of the motor or the shape of the exhaust system to achieve a certain exhaust note isn't fake, it's engineering and design. Conversely, dumping fuel into the exhaust system to create the illusion of overrun and get big pops and burbles is 100% fake. Not much different from just putting a sound file of exhaust noise in the audio system, except with that at least the rest of the world doesn't need to share in the fakeness. The only thing missing from my 981 Spyder's exhaust were flames shooting from the tail pipe.
Anyway, folks, I asked in my first post to stay on topic and don’t give comments about how juvenile or phony you think pops are. People at different stages of life have different tastes, let’s respect that. And no, not everyone who wants to have pops wants to show off or bother people. It shouldn’t be hard to believe that there exists a group of people who really like that sound! I don’t see anything wrong with having pops when PSE button is ON in twisty back roads. I love how 981 Spyder pops and not ashamed of this.
Again, thank you all for all the different ideas and perspective on this topic!
