❓ Frequently Asked Questions

Will this trigger a CEL (Check Engine Light)?
Yes, if you run catless without tuning. Our ECU calibration removes codes and unlocks full gains.

Is tuning required?
Highly recommended. You’ll get better performance, smoother drivability, and no emissions warnings.

Will it fit my vehicle?
Yes — all M276-equipped C43, C450, E43, and E450 models (W205 & W213). See the chart above for exact years.

Will these pass emissions?
These are catless components intended for off-road/track use where permitted. Check your local emissions laws.

Is there a warranty?
Yes — 12-month coverage on welds, flanges, and structural integrity under normal use, plus a fitment guarantee for listed M276 applications.
