Valvetronic Valved Sport Catback Exhaust System - Mercedes AMG GT (All Variants) 2016-2021
Lease for as low as $/week
Mercedes AMG GT – Valved Sport Exhaust System
H-Pipe Architecture • Valved Control • Titanium Construction
Overview
The AMG GT is a statement of power, elegance, and performance—but from the factory, its 4.0L twin-turbo V8 doesn’t deliver the emotional soundtrack worthy of the badge. The Valvetronic Designs Valved Sport Exhaust System fixes that. Designed specifically for the AMG GT platform, this system uses a precision-engineered H-pipe layout to unlock a more natural, balanced V8 character, while integrating valve control for total flexibility.
With valves closed, you enjoy a refined, subtle note perfect for cruising. With valves open, the system transforms into a motorsport-inspired roar that unleashes the GT’s raw personality.
