997.2 base with BB center muffler bypass only
I've been reading exhaust threads for 997.2 now for quite a while but most comments and video clips are about the S model and with PSE and or Gundo or Fister.
Please, anyone with 3.6 and BB, Sharkwerks, or AWE, etc. ONLY with no further exhaust or intake mods please chime in and provide sound clips if possible.
BTW, I have a cab with PDK so with top down, believe it or not, the stock exhaust does gurgle and pop on downshifts if you listen carefully..
Thanks. Sorry for yet another exhaust thread

Great timing as I was getting ready to make an identical thread.
Trying to decide between the mid pipe delete or Fister mod, but do not want to do both at first for fear that it will be too loud leaving my condo at 5am...

Just a bypass alone was very minimal for me. Between the bypass and the FD, I'd guess that the bypass contributes maybe 15-20% of the sound/loudness. I don't like overly loud cars so thought a bypass would be fine, but on a 997.2 base ... it wasn't.

Bypass on its own hardly does anything, aurally speaking. Unless you're planning to do Gundo (or have PSE), save your money as the two should be done in conjunction with one another.
And if you're worried about the car being too loud, buy a Prius.

I have a .2 coupe and only have the Fister bypass. It’s sounds pretty great and is a good compromise between civility and aural pleasure. There are times I want to add the center bypass but I don’t want my car to be overly loud. Go with the Fister alone. I think you’ll be disappointed with the center bypass. At least that’s what my research told me.

Haha, that's cute. For me personally, it is about having respect for my neighbors as mine gets driven everyday and I don't want to be "that guy" leaving at 5 in the morning with some obnoxious exhaust.
This is what I am thinking of starting off with.

Starting with the Fisters is a good choice. If you think they are too quiet then you can add the center muffler bypass.
If if you go the other way around, the change won’t be as noticeable as the stock mufflers will still keep your car too quiet.
I also did the Fisters first, and then added the center muffler bypass from AWE Tuning shortly after. BTW, I don’t think that your neighbors will be annoyed even with the Fisters + bypass.

I have an '09 C2 Coupe with PDK which I bought a couple of years ago which was (and is today) pristine with only 11K miles to boot. The first mod I did was to rip out the center muffler, replace it with Billy Boat cross pipes and while at it, removed the side mufflers and had a 2" Gundo hack done.
Net result: Yes, it's at bit louder but not overly but above 3K RPM, it's what a Porsche should sound like. So if you're worried about your neighbors, keep it below 3,000 around the neighborhood. Then after that it's all smiles and nods from those around you.

I got the standard Fister with 1.5 inch (I believe) pipes. Sounds nice but the 2 inch could be nicer. I've been thinking center bypass but not sure I need it. My ears don't work as well as they used to and the coupe deadens a lot of the sound.
Larger sway bars, semi solid motor mounts, and a center radiator trump the exhaust.

Here's my car with the Fabspeed cross-over, *just* idling. For the first time, I actually heard my car driving away (by a valet) last week, and I thought to myself "whoa, I never realized my car sounded nice!".

I have a 2010 base Carrera with just the Sharkwerks center bypass. From inside the car you cannot hear a difference from stock below ~6K rpm. As you near redline you hear a nice sound, but it is still quiet. Outside the car it sounds fantastic, and not at all loud. Just more “exotic” I guess. I do plan on picking up some Fisters soon though as just the bypass is simply to quiet inside the cabin.
