TNEER Valvetronic Exhaust System for Mercedes-Benz AMG C190 GT / GT S 4.0T 2015+
The Mercedes-AMG GT and GT S C190 are built around a mid-front mounted 4.0-litre twin-turbocharged V8 producing 469 horsepower in the GT and 522 horsepower in the GT S, the M178 engine developed exclusively for the AMG GT platform and representing AMG's first ground-up sports car since the original SLS AMG. The C190's transaxle layout, with the engine positioned behind the front axle and the gearbox at the rear, creates a weight distribution and exhaust routing architecture that is specific to this platform and fundamentally different from any other AMG application. The extended primary exhaust runs from the mid-front engine position through the underbody tunnel to the rear muffler section demand precise tube geometry across a longer routing path than a conventional front-engine layout requires. TNEER engineers this valvetronic system specifically for the AMG GT and GT S C190, with mid X-pipe placement and mounting geometry developed to the exact transaxle chassis layout of the platform.
Each section is formed from single-piece high-grade stainless-steel tubing using robotic pipe bending technology, producing continuous tube geometry throughout the system without the weld joints and flow disruptions of multi-segment construction. The mid X-pipe cross-links both exhaust banks at the mid-system junction, balancing pulse energy between the V8's cylinder groups. On a twin-turbocharged V8 platform with the specific routing demands of the C190's transaxle architecture, mid-system scavenging through an X-pipe contributes to exhaust flow efficiency and tonal coherence across the rev range, allowing the full character of the M178 V8 to express itself more completely through the system at every engine speed. The system installs to all factory mounting locations on both the GT and GT S, requiring no structural modification and maintaining correct chassis alignment throughout.
The ECU-controlled valvetronic rear mufflers manage acoustic output through the C190's existing AMG vehicle architecture without secondary controllers or aftermarket modules. Valves closed, the system maintains a composed tone appropriate for road use while presenting more of the twin-turbocharged V8's character than the factory exhaust allows at any throttle position. Valves open, the full acoustic output of the AMG GT or GT S M178 V8 is unobstructed and responds directly to throttle input and engine speed. The M178 is a unique engine in the AMG lineup, developed exclusively for the GT platform with a specific acoustic character that reflects both its twin-turbocharged V8 architecture and its transaxle mounting position. This system presents that character without the attenuation the factory exhaust imposes, on every drive.
Optional Downpipe Configurations:
For owners who want to address the primary restriction point in the exhaust path, TNEER offers two downpipe specifications that deliver meaningful performance and acoustic improvement beyond what the mid X-pipe and valvetronic muffler system alone provides.
- The race downpipes remove the factory catalytic converters immediately downstream of the turbocharger outlets, where back pressure reduction has the most direct effect on turbine behavior, spool characteristics, and mid-range torque delivery. On the M178's twin-turbocharged V8 architecture in the C190's specific routing configuration, the relationship between downstream restriction and turbocharger efficiency is immediate and measurable at every point in the rev range. These components are intended for closed course and off-road use.
- The 200-cell sport downpipes retain a high-flow catalytic substrate in place of the factory units, reducing restriction significantly while maintaining a level of emissions compliance appropriate for street-driven builds. For AMG GT and GT S C190 owners who require a balance between full-system performance and daily usability, the 200-cell specification delivers a substantive upgrade within a practical operating profile.
All downpipe components are fabricated from high-grade stainless steel and engineered to the same fitment standard as the valvetronic muffler system.
About TNEER:
TNEER is built around a single engineering conviction: the exhaust system is not a peripheral component. It is the primary interface between the engine and the driver's experience of it. Every system TNEER produces is developed to bring out the true voice of the engine it is built for, improving exhaust flow and delivering a distinct tone that is mechanical, raw, and directly connected to the character of the car.
The manufacturing process that defines TNEER's fitment standard is their high-tech robotic pipe bending technology. Rather than fabricating exhaust routing from multiple welded sections, TNEER forms each tube from a single continuous piece, bending high-grade material to navigate the spatial constraints of each specific engine bay without the diameter reductions, flow disruptions, and structural inconsistencies that welded multi-piece construction introduces. The result is an exhaust system with continuous tube geometry, perfect fitment to the platform it is built for, and no compromises in the routing that precision bending makes unnecessary.
For enthusiasts who regard sound and performance as inseparable elements of the driving experience, TNEER engineers each system to deliver both from the first throttle input.
Note:
- Downpipes are not CARB certified and may not be legal for use on emissions controlled vehicles; intended for off road use only.
- ECU tuning may be required due to removal of factory catalytic converters.
