Install Write Up & Pictures; GMG 996 World Challenge GT3 Sport Muffler Set
Bought directly from Fabryce @ GMG. Product Link
Great Customer Service on the sale and follow up. A couple of clamps were left out of the box, those that hold the can sections to the support brace. I checked and rechecked the box and all of the packing material but no go. I contacted Fabryce and he got a set out the same day, over-nighted to me from CA to NC.
The setup was packed very well, and the box was weighed as 24# by UPS.
Upon unpacking, it was apparent that this is a quality made setup. All of the welds look to be done by orbital machine and bends are mandrel.
For the install:
+ reuse the OEM double bolt slip joint clamps
+ reuse the OEM beveled compression clamps for the tips
There were no instructions and the pictures were a little hard for me to look at and translate to orientation. I had done my own exhaust install before on my previous C4S, so I wasn’t going into the project totally blind.
Why not keep the bypass pipes? I’m on the team that really likes the sound of the muffler bypass pipes, but I wanted tips that looked stock, and OEM tips could not be installed on them. This system lets me do that with near-MBPP sound.
I fired it up last night and had it idle for ~5minutes; I like it; its a little more subdued than the bypass pipes; I should have a better idea on sound this weekend.

Ha. No, Dell and his lift are much appreciated. I'd have tried to do this over there if I hadn't already tackled my first exhaust job with the C4S. 
Now, my first oil change on the GT3 was a whole other matter....

Ya, it's significantly louder than stock if it's the same system I had. Right around 102+ db WOT, but there is hardly any drone and it sounds freakin awesome!!!

I just got back from our local coffee & Porsche group usual Saturday morning drive. I can say that the sounds is ~90% of the muffler bypass pipes in tone and volume. Love it
