17. After the heatshield is installed use the scraps to patch or cover any open areas.
18. Slide supplied collector clamp over the inlet of the Yoshimura tailpipe and slide tailpipe onto stock header outlet.
NOTE: No exhaust gasket is used between the stock header and the Yoshimura tailpipe.
19. Install supplied muffler clamp heat insulator to inside of muffler clamp. Slide muffler clamp onto Yoshimura muffler
and slide Yoshimura muffler onto Yoshimura tailpipe. Line up muffler clamp ears with new muffler mount location
(shown in Fig. 11). Bolt the right side of the clamp to the subframe with the supplied bolt. Slide left side of muffler
clamp over the protruding bolt and install the supplied nut.
20. Install exhaust springs between the muffler and the tailpipe.
21. Check alignment of exhaust, then torque supplied collector clamp to 1.25 kg-m (9 lb-ft).
22. Torque muffler clamp bolt and nut to 2.5 kg-m (18 lb-ft).
23. 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.
24. Install rubber bumpers into the stock plastic muffler heatshields (see Fig. 13, Fig. 14, and Parts Diagram on the last
page).
25. Re-install tailpipe heat shield, rear fender, seat cowling, foot peg, and seat in reverse order of disassembly. Check for
proper operation of tail light, brake light, and turn signals before completion.
NOTE: The stock tailpipe heatshield has a rubber grommet on the back of it. Make sure that the rubber grommet is
inserted correctly into the tab on the subframe.
26. Check for proper clearance between new exhaust system and motorcycle. (i.e. Swing-arm, body work, 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 / in CA (909)628-4722.
Note: After starting motorcycle, it is normal for new exhaust system and muffler to smoke until oil residue burns off.
