Hard braking from around 250 km/h in 5th gear... clutch in (revs jump)... shift to 6th and clutch out... it did NOT like that ONE BIT!!

To clarify, maybe it´s just my lack of corerect terms to describe, I do not mean those ugly and artifical popping sounds a la M4 and other turbps. Just listen to a GT4, nothing cheesy or dishonest there.
Driving both back to back, GT3 brand new, I could not help bit find the GT3 rev match a bit too unspectacular. It simply lacked some sharpness and force, which seems to be coming along with the miles.

Heh-heh. The sound is underwhelming street driving while on break-in, isn't it? Anyhow, there are several threads on it, just search "exhaust" or "muffler bypass". Me, I am waiting for my first track weekend to decide if I want it noisier, or if it sounds just perfect blasting around a track full throttle. After break in, there is a nice baritone that comes on at and beyond 4K rpm when the cams change, then the scream as it approaches 9K. Not sure I want it any noisier.

In general, I think those outside the car are treated to much better sounds than the occupants (especially with windows closed). I'm sure it can be further improved with BBI/Graham Rahal center bypass, etc...

I'm with you 100%. It wasn't a GT4, but I notice the same difference from my Boxster GTS to the GT3. Frankly, on the rev-matching the Boxster sounded better. Just is what it is I guess. They've done something different with the rev matching in the new cars. We're not the first to notice it. I bet it's functionally better. I don't recall my Boxster ever "predicting" my shift. It did it's thing when the stick went into gear as far as I recall. And it definitely didn't do the matched up-shifts. So the system is different and it sounds different. Probably works better. Definitely doesn't sound as good.

My center muffler delete should arrive today. I only hope it is not over the edge at WOT, since the stock exhaust is already screaming @ 9000rpm.
In general, the GT3 is loud enough at WOT but a little tame below 5000/6000 rpm, we´ll see where it goes...

The center muffler delete is a must for any gt3. I was on the fence a few years ago with my 2015 gt3 until I went to an open house at GMG which many people attended. There were over 10 991 gt3/RS there and everyone had a center section delete. I spoke with a few people who had them, bought one and never looked back. It’s a must do along with clear side markers. These cars need nothing else

How is the popping "honest"?.. it's artificially created by the ecu on the lesser cars, but left out on the GT3, and GT2. I don't understand Porsche's logic here..
Exhaust won't change anything.. the popping sound is programmed in by the ECU... it's a branding effort, nothing you can do on gt3 even changing exhaust.. it all happens before reaching the exhaust.
