991.2 PSE vs base exhaust

Sorry if this has been hashed out before...
I'm moving from my GT4 for a number of reasons, one of which is a bad case of tinnitus that makes driving the GT4 aggressively an unpleasant experience. The thing sounds incredible, which is a shame.
So I've spec'ed the base exhaust on my 991.2 for that reason. That and I really don't like the way PSE looks (no offense). Sound clips I've heard from the PSE aren't convincing me that it's an absolutely essential option.
Anyone who's driven both variants - I'd be interested in any comparisons.

Also, I've never been a big fan of loud exhausts, but the option of hitting a button intrigues me. If I did get it, I'd likely have it off most of the time, but it would be nice to have fun with it.
If I don't spec the PSE, the other thing is that I don't like is the oval tips with the non-PSE base, so I'm thinking of just adding the dual tips, which of course will be cosmetic only and adds $1000 (CND) to my build. But for the extra $, to go with PSE, me thinks its an option I might regret.
Is there anyway to retrofit a dual tip PSE to a 991.2 base? Maybe from a 991.1?
So, my dilemma continues, any advice would be appreciated.

I would recommend getting PSE. The financial aspect will be negligible over the lifetime of the car. The center mounted pipes seem to be a new Porsche design direction, I expect future models to further go into that direction.
So while it's currently weird and outlandish, I think over time Porsche will win the public over and these new center pipes will become the norm. Just a hunch.
The bottom line is, don't worry about the looks. Now, that you no longer worry about the looks, let's look at what you're getting for your money. You get the ability to have both exhaust types. Quiet when you want it, loud when you need it. If you wanted to install something like that later on as aftermarket, it would cost you just as much if not more.

I have been researching the sound difference between PSE and non PSE on the 991.2 C2. I also have tinnitus. I came across a video of both systems. It seems the non PSE has flaps that open up as you rev the car from idle (test car was in neutral). This appears to be an automatic thing that you have no control over. With PSE, it also opens a set of flaps, but the demonstration showed that with PSE in the off position, the flaps stayed closed even as the engine was revved in neutral. It seemed to me that you actually have control with PSE to keep the exhaust quiet that you don't have with non PSE. So, for a guy with tinnitus, maybe PSE (in an odd way) is the better choice. For what it's worth, I test drove several C4S (991.2) coupes and regardless of engine speed and PSE on/off, I never found the exhaust noisy in the cabin. The car, in general with the windows up was quieter than the 991.1 with stock exhaust.

Not much experience with P cars as I just picked up a 991.2 with sport package this week.
I do have a lot of experience with V8's, turbo and supercharged cars from past ownership. In most of them, I either changed the exhaust, mufflers, inserted a golf tee to open valves or bought a remote to operate a mild to wild switch. I believe that sound feedback aids in the overall driving experience of a performance car.
My first impression of the PSE on the 991.2 is that it provides a good compromise between the quiet and the loud. I do not find it to be outrageous, but just enough to satisfy the visceral driving experience. As noted above, at highway speed, the predominate sound I hear is tire and road noise.
I for one, do enjoy the gurgling sounds provided for in deceleration.
My summary recommendation is if you do not have to sacrifice other desired options to meet your budget, I would get the PSE giving you the capability of on and off at your control. As a side benefit, it appears that PSE is desirable to many in the 911 community and if resale value is part of your plan, then I believe it will be beneficial.
Either way, you will still be driving one of the best "driver's car" on the market.
Best of luck

I now have 1050 miles on my 991.2 with PSE, sport chrono, and MT, and it seems to sound better today than it did from new. Maybe it's just my perception, but wonder if there is a burn-in period. When starting the car, I immediately put it in sport plus mode that eliminates the cackles but gives a nice exhaust note. I also tend to drive in lower gears to hear the note. At sixty-five in fourth gear, it sounds nice going down the parkway.
I seldom use 6th, and may have put it in the top gear once to try it. I think this car could easily be a five speed.

After just a week with my C2, I set the individual setting to no start/stop and PSE on. So yes i like the sound.

I have a 991.2 and with PSE on, sound is just barely adequate, without it almost as quiet as a Lexus if that is what you want (but I'm also comparing with my Ferrari 458, which sounds like a proper sports car).

We are testing a system this week. Will have a thread on it to follow up shortly!

IMO the central exhaust don't look too bad when looking at it dead on. The vents for the turbos on the corner of the bumpers help offset the central pipes. At other angles, yes, it doesn't look as aggressive compared to the quads (which I like too).

Hello Everyone,
I wanted to chime in as we have have a full range of 991.2 exhaust/tip upgrades for the 991.2 Non-PSE and PSE models. For those of you who want a Non-PSE style tip but more out of the exhaust sound, we can kick the exhaust note up a notch for you with our Center Muffler Bypass X-Pipe, Sport Cats, and/or Sport Headers. For those not quite satisfied with the PSE sound, we offer Sport Headers and Sport Cats to liven things up.
Here is a link to our 991.2 Carrera Product Page for you to go browse. Below are some pictures of the tips we offer and some sound clips of the exhaust systems in action. If you guys have any questions or interest just give me a shout and any of my contact in my signature

This video seems to indicate there is control over the flaps on a 991.2 C2 non-PSE, which results in a louder exhaust with a little bit of pops and crackles:

I've been trying to research this too and on the 991.2 C2, it appears there are flaps that control the exhaust sound and I'm not sure if they are automatically controlled or manually if you have the Sport Chrono package.

My conclusion wa that a PSE car with the defeat button was actually quieter with the system on defeat than a non PSE car and louder with the PSE button pressed. I ordered PSE.
