    new exhaust system and muffler to emit 

 

    smoke until oil residue burns off.

Care & Maintenance

Before starting vehicle, clean pipe thoroughly using 
a soft cloth and rubbing alcohol to remove any oil 
and finger prints. 

The color of the exhaust will change once the 
system has gone through a heat cycle of  15 
minutes or more. Color will vary depending on 
lean/rich conditions. 

Clean using a soft cloth and soap. Do not use 
abrasive materials as it will scratch the surface. 

Surface reconditioning services are available to 
remove scratches and undesirable discoloration 
due to extreme heat. Contact Yoshimura Tech 
Department at (800) 634-9166 / in CA (909) 628-
4722 for more information.
