Hi, I already sent you a message via the linked FaceBook account. However, it might be a better idea to contact you via rennlist! I came across a threat you started regarding the FVD valved X-Pipe exhaust on the 991 Carrera. Currently, I am looking for a new exhaust for the 991 Carrera 4S and the FVD X-Pipe seems like a very nice option. However, I cannot really find anything useful online (except that the build quality is great). Could you possibly tell me something about the FVD exhaust? How loud was it, what was the tone of the exhaust like and finally, do you maybe have a video where I can review the sound of the exhaust? The video you posted in rennlist is not viewable anymore. I hope to hear from you! Kind regards, Seger and Hans
