The Carrera and S are stuck with smaller turbos. The GTS and Power Kit give you more headroom. It's K16 vs. K24 all over again.

Regardless, the Carrera, S, and GTS all have the same potential. Some of us will opt for turbos larger than those of the GTS/Power Kit and make some real power...

I'm a former 4 time owner of Porsche TT's, the real daddy Pcar. Gains from software Tunes are real and the HP gains are amazing. The quoted gains from exhausts only are pure BS. Do you get, on some exhausts better breathing, yes, but 30 real HP and torque, not on the TT's. Software combined with exhaust the gains are real.
Us NA guys have to squeak out a few HP here and there but we do have a motor we can wind out to redline and a beautiful symphony.

200 cell cats thru less restrictive muffler on a turbo car is good for about 20-30 realistic HP yes, but its almost all in the cats. A tune with that would be good for an additional 75 HP conservatively. So yes, the tune makes the difference, but the exhaust on a turbo car does do more than NA. NA exhaust headers back is normally only good for 3-5 hp and you can actually lower the torque in low RPM from doing that at times.

I'd be interested in seeing if the Powerkit changes the exhaust note at all.

Well, not exactly identical on the 991.1...
To develop the Powerkit, a number of sophisticated measures were needed . The cylinder head intake ports have been reworked and given a polished finish. The stroke of the intake camshaft has been increased and the electronic engine management adapted accordingly.
The highlight of the Carrera S Powerkit is the newly developed variable resonance intake manifold with six plus one switchable valves. This innovation enables the system to switch between power- and torque-optimized geometries and deliver a boost in power output, particularly in the upper speed range. The extra heat generated by power increase is dissipated by an additional center radiator.

- Optional Sport Exhaust System with specially designed dual twin-tube tailpipes
- revised engine control unit including new engine compartment styling with a titanium colored cover and carbon inserts

STG, you know were talking 991.2 here right? I know all you 991.1 guys are sort of hand cuffed with the N/A motor for additional power but Looks like 32 hp according to Fabspeeds dyno chart on the .2S model. Most other manufactures are claiming similar gains with a full exhaust. I think I'll spend the $7K on an exhaust and Cobb tune and have a 3 times the power gain.

NA exhaust headers back is normally only good for 3-5 hp and you can actually lower the torque in low RPM from doing that at times.
On the S models the majority of the factory exhaust restriction is above 4k rpm and found in the factory headers and catalytic converters. From 4k rpm on it is a noticeable improvement in performance when equipped with our Sport Headers/Sport Cats, as shown in the graph below.
In regards to the 991.2 Base, we tested a Non-PSE with our full performance package installed (Sport Headers, Sport Cats, X-Pipe) and saw some pretty significant gains as well. The Base model exhaust system didn't see quite the peak gains of the S PSE, but you can see it saw some benefit even lower down in the curve.

I'm not surprised by the gains of exhaust (tune) on the new .2 cars.
Back in the day (2005ish) I achieved similar gains (30-50hp) on a much smaller 2.0 flat four from a WRX. Modifying a turbo yields much higher HP per dollar- this is transparent across all brands.

It's nice to get feedback from a few folks that actually have experience with exhausts and/or tuning on turbo cars. Evidently some of us know little more than what's posted or passed along on the 'forum' about how these cars work.

It took a few days but I finished the break-in process. The car is amazing/perfect/etc... Zero problems. ACC is better than expected. Voice control for Nav is the best I've used. I haven't fully explored the power - but I've got time.
Time to do something about the dead bugs and brake dust!
(Yes my center gauge is black - on purpose)
