Mercedes Benz AMG GLC63 M177 Decat Downpipes (2017-2021)

The ANTZ Performance Decat Downpipes for the Mercedes-AMG GLC63 and GLC63S are designed to replace the restrictive factory downpipes with a high-flow system that delivers significant improvements in performance and sound.

By eliminating the factory catalytic converters, exhaust back pressure is dramatically reduced, allowing the turbochargers to spool faster while improving throttle response, horsepower, torque, and overall engine efficiency. The result is a noticeably more aggressive AMG exhaust note and a sharper, more responsive driving experience.

Manufactured from 304 stainless steel using TIG-welded construction, these downpipes are built to withstand the demands of high-performance driving while providing excellent fitment and long-term durability. The complete system includes the downpipes, connecting pipes, and stainless steel clamps for a straightforward installation.
