After too much youtube'ing, I decided to take the plunge and give the Fabspeed side muffler bypass a shot. We'll see, it's all about experimenting!
Although, I ordered them last Thursday and Fabspeed called on Friday to say that they were out of stock and they had to be fabricated, which would take about 3-4 weeks.
guess I have to cool my anticipation just a bit.
-- I'm combining them with the Sharwerks x-pipe (muffler delete) which is already installed.

so I'll fill everyone in on noise level as well.

Anyone at all in Los Angeles with muffler bypass pipes on a 997.1 who'd be willing let me hear them? I want to officially decide if I'm keeping my afterhours mufflers or going bypass. Thanks!

I had the Afterhours mufflers on my 996 and loved the sound. The only thing was that there was way too much drone inside the cabin.
I was contemplating the Afterhours on my 997 but was not sure if there were any improvements made to elimination that drone.
I would be interested to hear about the noise and drone of the 997 gen 2 Afterhours mufflers on your car.

The generation 2 definitely has some drone between 2-3k rpm but its not bad and very bearable. While the exhaust is still quite loud, I would be willing to sacrifice more drone for a louder exhaust note. Which is why I'm debating going full bypass. I think the gen 1 Afterhours would be perfect but I can't seem to get my hands on a used set.

Mufflers have no effect on smog. Muffler bypass will pass. If by "full bypass" you mean cats too, then no. Cats are what will cause you smog issues.
