I know KYROCKS just posted a thread after installing our GMG Center Section and will be posting a sound clip / video soon and we will also have a full video and film crew out at Thermal this coming Friday for our 991 GT3 GMG track day which will also create many different sound clips. And since we will be on track, you will get full throttle upshifts through the entire rev range.....
If any of you are considering a Center Section / Muffler ByPass System, dare I ask if you could wait until we get this video with sound clips out on the RL Forum?

I'll say that I am surprised that all center bypasses look to be similar diameter pipe (we know they must be the same at the connection point to factory) but are tuned very different in sound.....it must be slightly different lengths of tubing that is creating this difference in sound. It's nice that they all have a unique sound to them.
GMG looks to get larger in diameter just after connection to side pipes....

Dear Meir,
thank you for your e-mail inquiry and your interest in Cargraphic products.
The flaps of our bypass pipe set will open and close like original and also the function of the factory sport button kept fully remained.
The factory flaps have only a diameter of 60mm and our 74mm exhaust flaps were especially produced for maximum power and the big diameter allows us to integrate them in our exhaust system without the need of any pipe reducer.
the Sport Button also open the Flaps? i'm confuse

We are taking a trip to Thermal Club this weekend and will have some nice vids to come!
Indeed, very nice car and sound! Excited to see/hear the video!
Size/length and material all affect the resonance frequency of an exhaust system. Our proprietary design along with the materials used create the unique sound that only our system can provide.

This sounds sexy!! These guys at GMG seem to have done a really nice job with the exhaust..I am just waiting on a better video from the guys with a GMG and I am all set to order one myself..Would be great if others are also in for a group buy..I saw 1 or 2 other people in the thread that are also interested in a group by too.
