M113K Supercharged AMG • Retains Factory Cats
Log Style Shorty Headers for Mercedes-AMG M113K
Faster throttle response, stronger torque and improved exhaust flow — while retaining the factory catalytic converters and OEM-style O2 sensor placement.
Retains OEM catalytic converters
OEM-style O2 sensor placement
Gaskets + studs included
Emissions tier: cat-compatible
This header bolts to the factory catalytic converters and retains OEM-position oxygen sensors. No emissions equipment is removed or bypassed. We do not currently list a CARB Executive Order (EO) number for this part — California-registered vehicles require a CARB EO for aftermarket headers, so confirm your local requirements before ordering. Outside California, check your state’s inspection rules.
These M113K shorty headers are built for supercharged AMG owners who want real drivability gains without the headaches. Expect a more responsive pedal, better low-to-mid pull, and a cleaner exhaust path that complements stock or tuned setups.
Pair them with a custom M113K ECU tune to maximise airflow and calibration for the supercharged 5.4L.

FAQ
Will these trigger a CEL?
Designed to retain OEM-style O2 sensor placement to help avoid check engine lights.
Do I need to remove the catalytic converters?
No — these are built to work with the factory cats. If you want the catless route, see our M113K mid-length headers instead, which are off-road use only.
Do I need tuning?
Gains are noticeable on stock calibration; tuning is recommended to maximise results.
