Was reading a few owners initial reviews of the 991 GT2RS, what many have said is that it has drone in some rev ranges. From my modding experience my understanding is that X pipe exhaust systems alleviate drone, which is why most tuners sell systems with these designs.
I was wandering why Porsche does not install these systems as stock, I appreciate they have noise, emission regulations and existing suppliers contracts.
