Hey,
After 2 months with me 911.2 GTS i am thinking about getting some more power out of it. I want to start with simple mods so i can reverse them in case warranty work.
I see everyone recommending doing 200 cells cats as best bang for buck. Which one is the best sound and performance improvement?
After that should i get cobb or custom tune after cells?

While I would question the actual HP improvement due to any exhaust modification (indeed, if you get any, it will not be noticeable to almost any driver), a proper tune should get you something. Having said that, most drivers in most driving conditions will hardly ever notice it. So, again, I say leave the car alone. Other than louder noise giving physic HP, the real benefit will be minimal. Use the money for a family vacation or give to a good cause. The 911 is a wonderful machine. Too many people "mod" so they can say they did.

If you take the factory exhaust and any aftermarket unit on absolutely equal cars under absolutely equal conditions (i.e., absolutely everything) the likelihood of getting much more than 5 extra HP is minimal. And I would opine that the average driver cannot feel even 10 HP let alone 5.

Not a performance mod but one that can provide a much better use experience. The T-design memory module that lets you defeat engine auto start-stop.
This should have been my first mod.

I wish it instead put the car in the last mode you had it in. I never drive in normal mode, so auto start/stop isn't an issue for me. I do wish I didn't have to switch it out of normal mode every time I start the car, though.

And I'd want to see a BEFORE the mods graph. It along with your AFTER mods will show a gain. Why? Because you never know how well the Dyno is calibrated. I worked in a defense lab most of my life taking measurements.
You lost 90 HP going through transmissions and shafts? Your Dyno graph shows 488 HP at the "engine".

As for mods, seat of the pants means squat! Noise does not mean power. lol
I'd sooner spend money on tires, brakes and suspension.
