I drove the GT3 with no cats, headers and oem center mufflers.
Sounds great with this much power added, weight reduction, workmanship and price point this setup is a no brainer.
Another additional big benefit that you possibly could get with a tune is that the flaps can be permanent open or closed with the exhaust button.
Of course you could just unplug it and drive it open all the time but the car is such a nice quiet DD that I'd keep the flaps active for when I'm using blue tooth for phone calls..

I got the headers installed a couple weeks ago. First impressions (good and bad).
1) It's loud - open valves at cold startup would be noticed at bike week in Daytona
2) once the valves close and you are moving, it's very livable and there's no drone. I agree with Matt - its about 30% to 40% louder, but not annoying at speed.
3) at WOT above 5k, it's REALLY LOUD. It sounds totally badass, like formula 1 badass, but I've also found myself going WOT less. It gets everyone's attention within 300 yards immediately.
4) seat of pants, there really seems to be more power. It spins the tires hard on the 1-2 shift now, which it did not do before.
5) the burble and pops downshifting will make a grown man giggle.
6) workmanship and fit are superlative.
A couple of minuses
1) there's a lot more smoke, so much that your clothes will smell like smoke if you roll the windows down before it has warmed up quite a bit.
2) I got a CEL after about a week - will have to figure this out. EDIT: CEL turned off by itself after a couple of days.
3) I'm not sure I needed MORE attention than a sapphire blue GT3 gets all by itself.
Overall, the GT3 is pretty user-friendly stock. You could daily drive it and take your wife to dinner if you wanted to. This puts it over the line. It's totally fine and livable in guy world, but it's a bit over the top in noise for a nice dinner date.
So the car has lost some of its Jekyll, but the new level of baddassery in terms of noise and power is worth it if you like mr. Hyde.
Every first to third gear run with 9,000 rpm shifts will make you laugh our loud, literally. Then start looking over your shoulder for cops or disapproving normal citizens.

Well the one negative he did mention was the CEL but since you are looking for more HP get a tune on top which will add HP and remove the CEL!

Cold start smoking I had with the stock system, I found that after a few trackdays car wasn't smoking at all, hopefully stays that way.
CEL, if you can stop by Autozone or whomever (it's free) and have them read it and clear it and let me know what it is (no nead to go to the dealer). could be any number of things as the car is adapting...
I giggle with every shift even at part throttle, there's a tunnel in Gig Harbor, over by where the pumpkin lives. Had Pat following me the other day and opened it up in there 2nd gear to 9k and he wasn't ready for it! Made his day!
We'll get info on the CEL and figure it out, just need to know what it is!

We're working on a fix for the cold start bark, is pretty common on emissions controlled cars as it's trying to get the cats warmed up quickly. We should be able to get it to be like warm start loud.

You don't get 40whp by being nice...

I got the same CEL myself after 40 km. It has not reset after restart.

We have 3 other RS running around with no CEL.
I sent an email for things to check on the installation, 20miles is really fast quick the only other car that had one like that was when the o2 sensor bungs were installed reversed. Feel free to call or email and we can help...
Should look like this.
