GAIN Catless Downpipes with Heat Shield & OPF Support – Mercedes-AMG GLE63 S (W167 / C167, M177, 2020+)

Unlock the full sound and performance potential of your M177-powered GLE63 S with the GAIN Heat Shielded Catless Downpipes — engineered for high-output, twin-turbo V8s demanding unrestricted flow and thermal efficiency.

Constructed from T304 stainless steel, TIG-welded for strength, and featuring precision laser-cut integrated heat shielding, these downpipes eliminate restrictive catalytic elements while maintaining OPF sensor compatibility (where required). The result: reduced backpressure, quicker spool, and an aggressive, raw exhaust tone.

Perfect for both stage 2 tuning and track-focused builds.
