During our holiday in Monaco last year, we saw this Mercedes AMG GT R Pro which has been fitted with a straight pipe exhaust system. The AMG GT R Pro has got a revised front fascia with a deeper chin splitter and extra side canards, fender louvers for extracting air from the front wheel wells and a gurney lip on the big rear spoiler hold the car to the road. It also got quite a few chassis upgrades over the standard AMG GT R. In this video you can see it driving around in Monaco making some lovely V8 noises.
