Emissions note
We design calibrations around repeatable performance and responsible engineering. Catalyst removal (often via downpipes) can create compliance issues and may not deliver the dramatic gains commonly claimed. If you have questions about setup choices for your goals, reach out—we’ll steer you toward the smartest (and legal) path.
