clearance between new exhaust system and
rear suspension (i.e. tire, swingarm, brakes,
rear shock, and etc.) If any problem is found,
please carefully follow through the installation
steps again. If problem still persists, please call
Yoshimura Tech Department at (800) 634-9166

12. It is recommended that the muffler and tailpipe
be wiped down with rubbing alcohol to remove
oil and fingerprints. This will help prevent
tarnishing of the finish after the exhaust is
heated up.
Note: After starting vehicle, it is normal for 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.
