I believe this is the ticket! I think it's the same solution that was finally determined as optimum overall on the 997 GT3's. Waiting to hear it on Money's car. Then also determine if the the header/200 cell cat combo make a big diff. Wondering if this center muffler will hold up without cracking on tracked cars?

"After talking with FVD and some long-time, knowledgeable 911 guys, I learned that I did it backwards. I should be replacing the side mufflers with a straight pipe. Then, to change to tone, replace the the factory center muffler with a tune M&M center muffler. The cheaper route would be just cap the factory center muffler and get some side muffler/valve delete pipes. I want to change the character and improve the sound of the car, so I spent the extra money to have them produce a center muffler for me."
Money - Are they producing a center muffler just for you or they have one for distribution?

Matt, Thanks for putting the video together. Sounds pretty good to me. It appears to solve the annoying sound transition from the valves, no valves! Would say this system is quieter than the Sharkwerks?
