Another exhaust sound data point

FYI, I've done more than 25 hours driving now and I think its developed a small amount burble on decel now, but only with revs above 3000 or so. Nothing like the 981 however. Long term ECU adapting??

Heres a couple requests.
stock vs just opf delete
stock vs opf delete plus exhaust
Do you think this will make power or do you need to change the cats? A dyno or dragy pulls would be nice altho both are highly variable.
Honestly if i had the option i would start with headers with high flow cats plus opf delete, and leave the stock muffler. Remove as much back pressure as possible with the least drone. But id end up doing the whole thing at the end of the day![hiha](https://rennlist.com/forums/graemlins/roflmao.gif)

The rear silencer will always be a bottle neck so it’ll be interesting to see the results
Another example of what I think is evidence that the stock car sounds great from the driver's seat. Skip to :56.

Everyone’s different I suppose but you have to remember this whole ‘stock exhaust sounds best’ thing is your opinion. That opinion is no more or less valid than my opinion that ‘stock sounds like an asthmatic vacuum cleaner running in the room next door’

My point was that it did not burble from the beginning, but now it does a small amount. Well, unless its the new car smell slowly feeding me the Kool Aid.

To echo some of the requests, I will want to keep the header and cat stock. So, please provide an option with those. Thanks.

You’re not going to convince every 718 to stay stock

You're missing my point. I'm not trying to convince anyone to stay stock, nor am I saying that stock sounds best either. I haven't said that in any of my posts. I'm merely saying that stock sounds really good. Nothing more, nothing less. The argument that stock sounds bad is nonsense peddled by the brap, brap, brap, brap crowd. It sounds great stock; like a real sports car.
For Christ,

I doubt that track video is of a stock exhaust. It sounds like there have been a few tweaks made.

As mentioned multiple times since late last year the ROW spec and EU spec cars sound the same. Simple as that.
We have had physical parts for over a year, compared and ran and there is no audible difference and contrary to popular folklore the inert OPF actually flows a touch less than the monitored EU spec OPF for a number of reasons.
The rumour gained momentum due to overly optimistic owners who were yet to receive their cars desperately hoping that their cars wouldn’t sound as pathetic as the EU spec cars. Made worse by some ROW owners who received their cars and continued to talk of ‘non OPF’ cars sounding better than EU cars based on nothing more than listening to YouTube videos.
Looks like it’ll take a little while longer for this to die out, especially given sales assistants are now regurgitating the same stuff![hiha](https://rennlist.com/forums/graemlins/roflmao.gif)
Planning to film a 981 GT4 vs 718 GT4 video soon with various exhaust options on each car. I’ll also film the 718 GT4 with ROW spec OPF pipes too to compare against the EU spec OPF pipes and hopefully help put the rumours to bed

If the ROW and EU 718 GT4s sound the same, then there is already a good video showing the difference of stock exhaust.

The stock sound is much better than I was expecting.
It doesn't come close to the 981 but I think many people will be fine with the stock sound.
It sounds good in its own right but if you're coming from a 981 you will probably want to mod if you like the pops/bangs.
Stock is plenty loud and even drones but my car is only on 200km now so the sound might change slightly as I break it in.
FYI I'm in South Africa, we have the inactive PPF (which according to some doesn't make a difference to sound).
