How many of us upgrade the exhaust?

Definitely doing at least valved side muffler delete for weight loss, and better heat dissipation on track. Sound is not a motivation.
Considering doing the side delete as part of Dundon package with both headers and air intake mods for optimal power but worried about Porsche warranty coverage for engine if something big happens down the road as I plan to keep this .2 GT3 for a decade.
So if I decide not to risk all that, will stick with basic valved side muffler delete.

As of 2019, in The People's Republic of California, there is a stricter law regarding aftermarket exhausts. Something to keep in mind if you live out here and are considering an exhaust that might be louder than stock: https://www.thedrive.com/news/25799/...ine-you-for-it

My various neighbor's barking dogs are much more of a nuisance than the occasional loud exhaust.

if this was my daily driver then no i'd most likely keep it stock or barely modify the exhaust. However since it's my sunday driving race car, full JCR inconel headers and titanium race pipe here we go

I never thought I would be researching exhausts on a Porsche 911 Motorsport car, thinking that stock must be one of the best exhausts out there to begin with, but here I am, getting caught up in it and perhaps sucked into the internet.
The exhaust thread seems to be for those who have decided that they will actually change the stock sound. But how many actually do exhaust upgrades on here? 10%? 25%? The majority? The few?
Is it one of those “must have” things (like clear side markers)? Or not?
Anyone did an exhaust and regretted it?
For those that have stuck with stock, does the sound get better with age (like many exhausts do)? I am currently at 400 miles.
Appreciate your thoughts!

PSE, it sounds good enough.
As far as removing the emissions equipment for extra sound, not for me, there's enough pollution as it is I don't want to add to it. Got 4 years of warranty to go.
Further, removing back pressure has been found to decrease mid-range performance, that's where most of us drive nearly all the time.

I plan to do the center exhaust delete with the MRBP blacked out center pipes... Saw some reviews on it here and people were saying it was great for the money.
I'm actually going to do a video documenting trying to do it myself. I figure I need to learn how to remove the rear bumper sooner or later so why not do it for the center delete exhaust.
Almost everyone I see here says that is the best simple set up.
Anyone noticed a difference in sound/power between the 4.0 and 3.8?

Yea I was wondering same thing. Not too many people say its overly loud but some people think its not loud enough and then remove the side mufflers then regret that later.

I’ve had my 991.2 fitted with Akrapovic slip ons only. Reasonable cost at around $3000 as it has improved sound while retaining usage of the sport exhaust button inside the car. 😊
