Both the Mercedes AMG GT63 and Audi RS6 C8 are engineering marvels, but performance enthusiasts know that downpipe upgrades are the key to unleashing their hidden potential.
Catted downpipes, on the other hand, include high-flow catalytic converters that offer a good balance—providing increased performance while maintaining emissions compliance.
The AMG GT63 is a flagship four-door coupe that blends luxury with track-ready performance. Equipped with a twin-turbocharged V8, it already delivers stunning acceleration.
