Default Porsche 991.1 Sports Exhaust
Hi all

Am I correct that in the picture attached, this is the original Porsche Sports Exhaust of the 991.1?
I was wondering what these cutouts at the tips of the exhaust are, on this 2013 Carrera 3.4.

Thanks

Looks like it. Here you will see that those cutouts are standard: https://rennlist.com/forums/attachme...n-img_0059.jpg

What purpose? don't know sorry.

Most likely the cutouts are for tuning the sound and/or damping out certain resonance frequencies.
