G90 Owners will know that exhaust note is one of the weak points of the car.
Since the G90 has a new exhaust system, I was wondering if anyone has gutted the midpipe to make the exhaust louder.

Many people (including myself) has done this on F90 M5, but no info/data available on the G90's.

Any pics would be much appreciated and helpful to the community.

Thanks!

The European version has the opf instead of the big resonator in the USA version see the pic (very surprising and I think it explains why usa version sounds even worse the European and it is the first time that a usa version has a resonator to replace opf instead of a straight pipe like the f90 m5)
Solution just remove this bigresonator and straight pipe this portion

The second pic in blue is the second resonator in both cars usa and European version and I think if straight piping not enough this can be replaced with x pipe
Hope that helps
I came with all this after observing my car and other European cars
I also may go this route

My f90 I used a Dinan x pipe and afterwards the sound was pretty good, I plan on doing the same to the G90, secondary DP and x pipe.

I did the same with my m8 but this car has 2 resonators

It’s only a matter of time before parts start to be released - in the mean time this gives me time to get the comsmetic done. I am sure the g90 will have even more pops and bangs once they start releasing tunes.

I will start with removing the big resonator and straight pipe this pat and this should sound like stock f90
