For what it's worth...
I uploaded a video of the SQ4 stock exhaust. Planning on replacing center pipes with Bertocchi (Japan local brand) exhausts which give it a slightly higher pitch.

Nice work WAKA. Love the closed valve to open valve comparison.

Thanks guys. I took the video with a Sony HDR-AS100VR.

I am personally a big fan of comparison before/after videos and plan to create one after upgrading the center pipes.

Similar to what I had created for my Quattroporte (see below).

What was required to instal the Bertocchi Center Pipes?
