Another exhaust sound data point

I’m sure you all want another sound clip about as much as another hole in the head, but I was able to finally listen to one of these cars in person today, so I thought I would share. This is a Canadian Spec model and the SA insists there are no OPF in the car, not even inert cells in place of the OPF. He says the chambers are empty “to save weight and cost”. I don’t know if that is true or not, but the car is not what I would call “quiet” and is quite raspy...at least from the exterior. It doesn’t sound like a GT3 either mind you, nor should it. Rev’d to only 4K rpm briefly.

Sounds great to me. I keep watching all those Asian track videos of the 718GT4 on YouTube and I think the car sounds awesome.

I know what it will sound like in my garage now.
the valves are open at low rpm, which is most of this video. The 4k rev happens against a cinder block wall so it’s a stretch to think about what that sounds like in real driving conditions.
I also think it’s highly likely that this is a case of a grossly misinformed SA. The Canadian cars aren’t going to magically get a full OPF bypass when overwhelming evidence states ROW gets an inactive matrix.

I’ll take the hole in the head please!
no offense to you personnally 4midable, but again, these videos (indoors/coldstart/different mike position...) dont tell anything about the exhaust sound... we need side by side outside videos of hot exhausts. I agree about the SA not knowing anything about OPF’s...

I drove both the 718 GT4 as well as 718 Spyder last week and really liked how they sounded from behind the wheel. They both roar great at idle but valves close almost immediately as you roll away and it gets very quiet for bystanders. They definitely sound muffled compared to the 981 even after they open up later in the rpm band. The Spyder with roof down sounded a lot louder than the GT4, I guess that was expected. Under full throttle past 5000 rpm they actually make great noise and in some way more mature without the artificial overruns. The valves seemed to open and close inconsistently at times when rolling around town, not sure what that was about and I hope by keeping them open at all times that may be enough for most of us to enjoy the car. I came away loving the experience and ordering a Spyder.

You can forget that sound clip above being representative of actual running noises, it only sounds like that for the first 30 seconds or so while it does the cat warm up procedure on cold start.
Same as the 981, but it goes for longer and sounds a slightly different. The car also does a mini warm-up procedure if it has cooled down somewhat, but not cold.

You get used to them ![hiha](https://rennlist.com/forums/graemlins/roflmao.gif)
Unfortunately, your SA in misinformed. Like in America and Canada, South Africa get an OPF/GPF with an inactive matrix. Listen to this clip, the first car to arrive in SA with this system. Sounds good.

I'm loving it.We are still in lockdown so it's extremely difficult to do some moving clips and drive by's without creating attention. It will be difficult to explain to the cops why this is an "essential service"
. Hopefully that will change soon.
