Porsche 991.2 GT3 R (GT3 Class) w/ Unmuffled Exhaust: Pure 4.0 N/A Flat-6 Sound!

I think I’ve never explicitly said it but unconsciously there has always been a small desire to be able to hear one of the GT3-class Porsches with a fully unmuffled exhaust.

The opportunity happened last weekend at Mugello Circuit during the 2021 12h of Mugello race organized by Creventic as the first of two Italian rounds of their 24h Series. Typically the upgraded 991 Mk2 (991.2) version of the “R” comes with a visible muffler on the rear of the car, but despite that it still manages to be one of the most melodic sounding cars in the GT3 class and it’s also loud enough for my liking.

But thanks to Herbert Motorsport team, one of their 991.2 GT3s was fitted with that straight exhaust during the whole racing weekend. And it sounds ridiculous compared to the already loud standard R’s. Of course in this form the 4.0-litre naturally-aspirated flat-6 engine could only have echoes of the beloved GTE-class 991 RSR 2017. But even if sometimes tones and notes are exactly the same, the RSR still keeps the ”loudest race car” trophy among them.
