SLE Mercedes-AMG GT, GTS, GTC & GTR C190 (4.0T M178) 2015–2017 Catless Downpipes

The SLE Catless Downpipes are designed to bring out the full potential of the M178 twin-turbo 4.0L V8 found in the Mercedes-AMG GT series. By removing the restrictive factory catalytic converters, these downpipes improve exhaust flow, reduce backpressure, and deliver faster turbo response along with a more aggressive, motorsport-inspired exhaust tone.

Fabricated from T304 stainless steel and fully TIG-welded and back-purged, these downpipes are built to handle high heat and boost, making them a perfect upgrade for tuned or track-focused AMG builds.
