The system consists of long tube headers, sport side mufflers (brackets included), catted x-pipe and center delete with tips, all made by M&M in Germany.
Sounds amazing but too loud for me so going back to stock.
Found a stock system so these are being pulled from the car this week and will post better pics. Lemme know if anyone is interested it this. It screams!!
I went from a stock system to an RSS center Delete. First day, I thought is was too loud then got used to it and craved that center delete sound. Did I gain power from the center delete? None at all. Then I removed it and installed this Brombacher full system. Longtube headers, 200 cell cats and OEM quality side mufflers.
After installation I started the car and the sound, although not as loud, was back to the OEM flat 6 sound but deeper in pitch. It's a great sound with no drone whatsoever, in any gear at any RPM. The increase in Power was immediately noticable. Car pulls like a freight train now. With the center delete, the car seemed to run out of steam, like it lost some torque. I'm extremely happy with my system and the increase in power which is incredibly noticable.
Here's a picture of my system before I threw it on the car. Special thanks to MJ Speed for helping the snag I had with a few missing parts. He reached out and did all the legwork for me.
Few pictures so you can see what GBX is selling. I have no interest in this thread or his sale. Just trying to give some insight to anyone thinking about this system.
Test fitting the system
Stock 997 GT3 header vs. Brombacher long tube header
Where are the muffler brackets? Stock brackets won't fit on this system and ordering them through Brombacher M&M will cost pretty penny. I spent a little over $1,000 procuring brackets for my system.
If you installed the stock system with the Brombacher brackets, you'll need to get stock brackets and replace. The Buyer will need those Brombacher brackets or he's end up paying almost full price for your system. $5,000 plus $1,000 for new brackets.

M&M Muffler brackets come with the system. Just not pictured.
I used OEM brackets on the OEM muffler when I went back to stock.
I'm going to second this system. It's one my car and I'll pull on a stock .1 GT3 all day long. The power increase is very noticable.
As far as the sound, GBX states that the sound is too loud for him. IMO, it's not loud at all. It's a deeper sounding stock flat 6 sound. As soon as I fired up my system, I was like wow, my long lost Flat 6 sound is back. The center delete, although a great sound, isnt' the Porsche sound we are all familiar with. The Brombacher brings that sound back in a slightly deeper tone and it does scream when you get on it. Maybe that's where GBX is saying that it's louder, which would be true. Nonetheless a fantastic system all around.
On another note, I also purchased my system used with the 200 cell cats. No check engine light. Passes smog everytime with fllying colors. The only other system that I think will give it a run for it's money would be the Dundon, which I have yet to experience.
