991.2 GT3 PSE sound

[Claret m]

Hi All
Coming from a 991.1 4S with a sports exhaust, I am really disappointed by the PSE on my new GT3. It hardly sounds any different, apart from slightly more bass.

What I am missing?

I'd highly recommend JCR's titanium valved side silencer bypass and have the same on my 991.2 GT3. Keep the standard rear silencer, lose nearly 20kg from behind the rear axle, sounds an awful lot better, and the OEM valve button still works.

Won't that invalidate an OPC Warranty though (assuming the OP has a warranty)?

Indeed, switching to sport does not have a major impact. However, on 7.2 as well as 1.2 GT3s i find it makes the sound richer. I understand the impact is potentially bigger outside of the car than for the driver. Given the engine sounds is glorious already, I don't feel short changed

No. A remap would, which is why no one's touching them on these engines.
