AMG GT 3.5" CATTED DOWNPIPES - C190 GT/GTS/GTC/GTR M178

HIGHLIGHTS

PROFILE

The factory AMG GT downpipes are highly restrictive, designed primarily for economy and noise reduction rather than performance. As power levels increase, these restrictions lead to excessive backpressure, higher exhaust gas temperatures, and reduced turbo efficiency.

The ARM AMG GT C190 3.5" Downpipes are engineered to remove these limitations and unlock the true performance potential of the M178 twin-turbo V8. By dramatically improving exhaust flow directly after the turbochargers, these downpipes deliver faster spool, sharper throttle response, and substantial horsepower and torque gains when paired with tuning.

Designed as one of the best power-per-dollar upgrades for the AMG GT, GTS, GTC, and GTR, the ARM C190 AMG GT Downpipes support aggressive street driving, track use, and high-performance builds while maintaining precise OEM-level fitment.

CONSTRUCTION

The ARM AMG GT Downpipes utilize a CNC machined ball-and-socket exhaust connection allowing angular movement and secure sealing between the upper and lower sections of the downpipes.  The lower 3.5" sections improve the tone of the M178 exhaust note further, giving your C190 AMG GT the sound it deserves. 



The ARM AMG GT Downpipes utilize OEM-style midpipe connections in order to connect with the factory catback section, or any aftermarket exhaust that mates up to the OEM downpipes.  One adapter has a ball-and-socket connection and the other is a standard slip-fit connection, just like OEM.
