Overview
The Mercedes-AMG M177 factory downpipes carry an OPF filter that is the primary exhaust restriction on E63 and GT63 applications. This catless kit removes the OPF entirely — significantly opening the exhaust path from the twin turbos and supporting tuned M177 power targets.
- Removes the primary restriction in the factory post-turbo exhaust path
- Improved turbo spool — the turbo recovers and builds pressure faster
- More defined exhaust tone under load
- Stainless Steel construction for longevity
Engineering Focus
SS304 Stainless Steel with integrated heat shield. The OPF sections are deleted and replaced with free-flowing Downpipe sections — a direct improvement in post-turbo exhaust flow on M177 applications.
Driving Experience
A catless Downpipe is the clearest sign a build has moved past stock thinking — every gram of OPF restriction gone from both sides of the M177's twin-turbo V8 at once. It's a track piece, not a daily-comfort one — pair it with a tune to get the most from it.
