CARE & MAINTENANCE

Auto parts like stainless steel headers naturally develop heat discoloration, oxidation, and road grime over time. Always allow the exhaust to cool completely before cleaning. For routine care, wipe the surface with a soft cloth and a non-abrasive metal cleaner. To restore heavier oxidation, wet-sand gently with soapy water using fine-grit sandpaper (800–1,000 grit), then finish with a quality metal polish. Remove all residue and fingerprints before starting the engine, as oils can stain the surface during heat cycles. A light golden tint after driving is normal and does not affect performance.
