QHCE C-Class Catback — Mercedes W205 (C200 / C250 / C300)
VALVETRONIC
Whisper to wide‑open.
Valves shut, it’s refined enough for a 6 a.m. start. Valves open, it roars. Flip the valves and hold the throttle — feel it climb.

W205 C-class with the four-cylinder feels under-served by Mercedes — the C-class deserves a real voice. This catback delivers without the cost of going AMG.
