If you are doing your own install with any of the exhaust systems....
Using 15-18lbs on all the bolts is a good number.
After a few hundred miles or a couple of weeks, I would go over the whole install again and recheck all bolts to make sure they are still tight and all mount points are good and nothing is rubbing or vibrating.
I have the full Tubi installed and have absolutely no vibrations. Of course, I am one that like to take the full bumper off. That way I can give a full exam to the rear end.

The dealer I'm going to (Town Porsche) seem to be great and apparently have done installs for Sharkwerks in the past. I'll make sure everything is coordinated correctly and will also be attuned to any vibration.
I'm going to wait for the center muffler to be done before getting the sides done... or maybe will leave that one for next year to get some added variety every year!
Thanks to all for the input.

Yes. My best was a 12.0 @ 115. The car would run 12.1 run after run! 
Much faster than any magazine or manufacturer claim!
The only two mods, the AWE secondary bypass (almost identical to the SW) and BMC filters. And that's with a 265lbs driver and half tank!
I had started a thread months ago with videos and the timeslip.

I don't agree that it doesn't do much. My GTS has PSE, but running the SW pipe with PSE off, I did notice a difference. In fact, when I brought the car home after having it installed, my wife remarked we didn't need the SW pipe, which we had been discussing, since the car really sounded good. She didn't know I had had it installed.

You actually had a conversation with your wife about the SW center muffler delete? "Our" Carrera S cab is actually my wife's DD, and I can't get her to commit. And we live just across the Bay from Fremont, where SW is HQ'd, and I have a buddy there so we could hang out while the job was being done. Yikes.
Alex and Dan take good care of me as they did with my ex-6GT3.

On our first group ride, we were next to a few other 911s discusing the exhausts. One had a the gundo, one had the fister, another pse. Ours was the lonely stock. After hearing the others, she said, I should get an exhaust like those.
Once I told her the deal I was getting on the Tubi compared to the bypass + gundo, I got the go ahead.
I was going to do it anyways, but at least now she gets some of the blame when the credit card bill comes.
