SLE Mercedes-Benz G63 & G65 AMG W463 (4.0T / 5.5L / 6.0L) 2012–2018 Catless Downpipes

SLE Mercedes-Benz G63 & G65 AMG W463 (4.0T / 5.5L / 6.0L) 2012–2018 Catless Downpipes

The SLE Catless Downpipes are engineered to unleash the full performance potential of the Mercedes-AMG G-Class W463 models, including the G63 AMG (M157/M177) and G65 AMG (M279) engines. By removing the restrictive factory catalytic converters, these downpipes increase exhaust flow, reduce backpressure, and improve turbo response while delivering a deep, aggressive exhaust tone.

Constructed from T304 stainless steel, and TIG-welded with back-purged seams, these downpipes are built to handle high boost and extreme temperatures — ideal for performance builds and tuned applications.
