Care & Cleaning
Care & Cleaning
Keep system free of dirt and moisture. Store in a cool, dry place. Make sure vehicle is
completely cool before maintenance.
Stainless Header System: Polished stainless steel pipes will turn a light golden hue
after a few heat cycles, this is a normal characteristic of high quality stainless steel.
Clean using a mild water based spray cleaner. Always apply cleaner or polish with a
soft, clean cloth.
Titanium Header System: Polished titanium pipes will experience color shift ranging
from deep blue/purple through amber after a few heat cycles. This is a normal
characteristic of high quality titanium. Clean using a mild water based spray cleaner.
Always apply cleaner or polish with a soft, clean cloth.
Polished Aluminum Canisters: Use an aluminum or mag wheel polish to restore the
bright nish to factory spec.
Brushed Aluminum Canisters: Clean using a mild water based spray cleaner. Always
apply cleaner or polish with a soft, clean cloth.
Carbon Fiber Canisters: Clean using a mild water based spray cleaner. Always apply
cleaner or polish with a soft, clean cloth. Always make sure the berglass packing
inside is in good condition and not burned out, as exhaust heat inside an empty canister
will deteriorate the carbon ber sleeve.
