Own a 17 C2s. Drove the 17 C2s and 17 GTS back to back at PSDS in Birmingham. I could not tell much difference in the sound quality.

IMO, interior sound deadening is your problem, not as much the loudness of the exhaust.

GTS does have more get up and go..significantly more hp and torque.

Handling wise I have the Sport PASM and PDCC on my own C2S and I could not tell much difference between that and the GTS.

Just keep your stock stuff...as long as there isn't a tune you're doing with it that will show differing boost pressures achieved, you can just revert it back to stock should an issue occur.

There is NO difference between the exhaust note of the 3 versions in the 991.2 (base, S or GTS) equipped with PSE. I've tested it more than once

It kinda bothers me that there is no 4 tipped exhaust in 991.2 gts. Car looks awesome with those dark details but that two piped (mandatory) option really annoys me.
If I were buying that car, I would get C4 rear bumper and then buy aftermarket 4-tipped exhaust

Does anyone here knows is this doable?

That's what i plan to do.

I have a full Akrapovik system coming in a few weeks, that will not require a tune. I am using an O2 extension of sorts to avoid CELs.
