SLE Mercedes-Benz G63, G500 & G550 W463 (4.0T) 2018+ Catless Downpipes

SLE Mercedes-Benz G63, G500 & G550 W463 (4.0T) 2018+ Catless Downpipes with Heat Shield

The SLE Catless Downpipes with Integrated Heat Shields are built for maximum performance and reliability on the W463 Mercedes-Benz G-Class models equipped with the 4.0L Bi-Turbo V8 (M177) engine. Designed for the G63, G500, and G550, these downpipes replace the restrictive factory cats to deliver significantly improved exhaust flow, quicker turbo spool, and a deep, aggressive exhaust note.

With integrated thermal shielding, these downpipes reduce under-hood temperatures and help protect surrounding components — making them ideal for high-performance street builds or track-ready G-Wagens. Constructed from T304 stainless steel, and fully TIG-welded and back-purged, this setup is built to handle extreme conditions.
