I've been working with the good people at FVD (thanks Rhonda and *****) regarding developing headers for the GT3/RS that will work and make definitive power. Let alone sound awesome.
FVD has teamed up with German builder M&M and have been working on R&D for this project.
The system is not complete but here are pics of what's cooking.
This system will not have side mufflers. Shown are 200 cell cats and the final design of the rear section is still in flux. All will depend on what results it will have in making added power but must not hurt power.
The sound and db levels is another issue to consider.
You can keep the stock rear center section as on option.

Here are some pics. IMO these are real headers.






I can't wait.

Cheers

Nice Juan!
excited to see/hear the results
I got real hp with some custom headers/exhaust on my 996-3

 

Juan,
Those look like some serious and powerful exhausts and kind of reminds me of a bazooka. I bet you will have some horsepower gain from it. Please post video of your ride after the installation of those BAZOOKA. Good luck!
