Remember the RENNtech Mercedes AMG GT that the German/American tuner had boosted to 590 horsepower? Well, they have now fitted the car with a custom sport exhaust system as well, and it sounds like, we imagine, what God sounds like when he yells at people in hell for all the dumb stuff they did when alive!

The exhaust system designed for RENNtech Mercedes AMG GT is a stainless steel unit with bespoke downpipes made from the same material, with 200 cell sport catalytic converters integrated into the design. No doubt this treatment will also be good for the car’s power output, but to know about the numbers we’re going to have to wait for the dyno test. For now you can enjoy the amazing soundtrack and compare it with the stock system:

RENNtech Mercedes AMG GT also gets a software upgrade exclusively developed by the firm for the M178 engine. With just a few lines of code, RENNtech has managed to boost the output of the GT’s 4.0 liter bi-turbo V8 to 591 horsepower and 693 Nm of torque. That results in a quarter mile time of 11.28 sec at 128.11 mph, and a verified top speed of 313 km/h.
