W205 C300 SwitchPath™ Exhaust

Valve open for aggression, valve closed for sophistication. All via AWE Tuning’s custom designed SwitchPath™ Remote. Easy.

Equipped with a 180 Technology resonator in the midsection, a valved straight section on the driver’s side and a muffler on the opposing passenger’s side in the rear, the AWE Tuning SwitchPath™ Exhaust is capable of changing soundtracks instantly with the touch of a button. Drone-free mood control.

W205 C300 Touring Edition Exhaust

The W205 C300 Touring Edition Exhaust features AWE Tuning’s proprietary drone-canceling solution, 180 Technology, enabling the perfect tone, minus drone — delivering the ultimate mix of performance and refinement out of the C300’s 2.0T engine. A direct bolt-on, straight-through design, the Touring Edition Exhaust delivers a civil, smooth soundtrack throughout the range while providing an enhanced in-cabin driving experience.

Sound Perfection: AWE Tuning 180 Technology

As exhaust gases exit the W205 C300 engine and flow into the AWE Tuning 180 Technology equipped resonators, they pass through strategically located ports, and into reflection chambers. Sound waves, carried by these exhaust gasses, bounce off the walls of the reflection chambers. By controlling the size and location of the ports and the chambers, we also control when the sound waves exit the chambers. The specific timing of when the reflected sound waves rejoin the main exhaust flow creates a one-hundred-and-eighty-degree out-of-phase sound wave that cancels out problematic frequencies.
