7. Install the stock flanges, retaining rings and O2 sensors onto the supplied front and rear headpipes.
8. Install the front headpipe (with stock gasket in place) onto the front cylinder using the stock nuts but DO
NOT TIGHTEN at this time.
9. Position the supplied #27-61 MSC muffler clamps with hex head facing the direction shown in FIGURE 3
over the inlets of the muffler.
10. Insert the rear headpipe into the top inlet tube of the muffler. Make sure to slide it in as far as possible.
11. Install the rear headpipe and muffler assembly (with stock gasket in place) onto the rear cylinder and slide
the lower muffler inlet on to the front headpipe. Rotate the rear headpipe as needed to align it with the
cylinder outlet. Use the stock nuts to fasten the rear headpipe to the cylinder but DO NOT TIGHTEN at this
time. Make sure the front and rear headpipes are pushed in as far as possible into the inlets of the muffler.
12. Secure the muffler assembly to the exhaust mount bracket using the (2) supplied 5/16"-18 bolts but DO
NOT TIGHTEN.
13. Make sure the muffler assembly, front headpipe, and rear headpipe are straight and parallel and tighten in
the following order; headpipe flanges to the cylinders (slowly tightening opposing nuts), muffler assembly to
the exhaust mount and finally the muffler clamps. (NOTE: The muffler clamps should be flush with the end
of the muffler inlets when tightened. See FIGURE 3. If the muffler clamps are slid past the slots on the
muffler inlets the clamps will not tighten properly).
14. Plug the O2sensors back into motorcycle wire harnesses.
15. Unscrew the small HS-24 clamps and feed the tail end of the clamp through the clips on the inside of the
heatshields. See FIGURE 4 for proper positioning of the clamps on the heatshields. (NOTE: The arrows
point to the positioning of the hex head of the clamps. The hex head of the clamps should be accessible for
tightening but not visible when the heatshields are mounted to the pipes.)
16. Unscrew the larger HS-28 clamp and insert the tail end through the clip on the inside of the bikini
heatshield. See FIGURE 4 for proper positioning of the clamps on the heatshields. (NOTE: The arrows
point to the positioning of the hex head of the clamps.)
17. Install the front heatshield first. (NOTE: Spread the hose clamps apart slightly to make it easier to slide
them over the muffler assembly and headpipes.) Adjust the heatshield as far back as possible on the
headpipe so that it will align properly with the bikini heatshield. Make sure the clamp on the muffler inlet
does not interfere with the heatshield and is aligned as shown in FIGURE 3. Snug the heatshield clamps
but do not tighten.
18. Install the rear heatshield the same way as the front heat shield. See FIGURE 4.
