SLE AMG GT43 / GT50 / GT53 & AMG 53-Series M256 Catless Downpipe (2018–Present)

SLE AMG GT43 / GT50 / GT53 & AMG 53-Series M256 Catless Downpipe (2018–Present)

The SLE Catless Downpipe is built for maximum performance and sound on Mercedes-AMG models equipped with the 3.0L turbocharged inline-6 (M256) engine. Whether you drive a GT43, GT50, GT53, or any of the AMG 53 models — including E53, CLS53, GLE53, or GLS53 — this downpipe replaces the restrictive factory catalytic converter for dramatically improved exhaust flow, sharper throttle response, and a deep, aggressive tone.

Constructed from T304 stainless steel with TIG-welded and back-purged craftsmanship, this downpipe is designed to withstand high-boost conditions while ensuring a perfect OEM-style bolt-on fit.
