Well folks come to update the topic.
I was on holiday in the Algarve and was the first trip with the removal of the central silencer.
I thought it was worse, but the fact is that it does not appear intrusive. It is noted of course, but it is not of those things impossible to hear. Of course, when you step hard on the throtle, but with cc connected to steady speeds is bearable without problems.
I completed with this all over 66000km with the car and so far everything rolling smoothly, in fact is quite vigorous and full of soul, as you can see the video and photo ......
Power measured without repro's. It is stock, and just as you know I have the least restrictive exhaust ....
Hug to everyone.
P.S: the video came later!
