How do you install M4 exhaust on 2008 cbr 1000?

Answer 1

Remove the rider's seat and lower cowl. Please see pages 104-106 of the
Owner's Manual for details of removing the lower cowl.
2. Disconnect the exhaust valve servo motor located under the rider's seat.
First, unclip the wiring connector from the under tray by depressing the tab
under the connector sliding it to the left. You can now separate the
connector.3. Remove the bolt securing the servo
motor to the under tray. Pull the
motor off its post and disconnect the
cable.
4. Pull the cable through from below, replace the servo motor, reconnect the
wiring and clip the connector back in to place.
5. Remove stock muffler by:
a) loosen the slip joint to header clamp
b) remove rear mounting bolt from rider's footrest hanger
c) detach the footrest hanger
d) rotate the muffler to one side and pull it off the headers
6. Remove heat shield from the back of the footrest by taking off the small
bolt at the front. (careful: the bolts are quite soft headed and require care
when removing.) Undo the rear bolt which has a nut on the back.Assembly
1. Slip the TMR muffler onto the headers at an angle so it slips under the
suspension linkage. Once engaged, roll the muffler up and behind the foot
rest hanger and then push the muffler fully home against the stop on the
headers.
2. Replace the footrest hanger and tighten mounting bolts.
3. Put the stock muffler mounting bolt back through the footrest hanger
mount, through the strap bracket and let it rest there.
4. Tighten the muffler clamp firmly. If you have a torque wrench torque to 25
foot pounds. Make sure the muffler is tightly attached and there is no
movement.
5. Re-attach the lower cowl as shown in the Owners Manual.
6. Tighten the front two stock bolts on either side of the lower cowling.

7. Take the trim piece and place the front underneath the rear edge of the
lower cowling, over the muffler exit at the back and behind the footrest
hanger mounting bolt at the top
8. Push the mounting bolt through the tab at the top of the trim piece and
replace stock nut finger tight.
9. Replace the stock bolt through the rear of the lower cowling, through the
hole in the front of the trim and tighten to the frame.
10. Align the bracket on the back of the muffler with the hole in bottom, rear
tab of the trim piece. Then take the small, black cross-headed screw from
the kit, put it through the hole in the trim, engage the well nut in the muffler
bracket and tighten the screw.
11. Check there is clearance between the trim piece and all the way around
the exit pipe. There must be no contact between the carbon and the
muffler. If there is contact go back and loosen the muffler clamp at the
headers and twist the muffler to locate the exit in the center of the trim.
Don't forget to tighten the muffler clamp again!
12. Tighten the top mounting bolt through the footrest hanger.
13. On the right hand side, place the piece of plastic trim grip over the join
overlap on the lower edge of the carbon trim piece and lower cowling.
14. On the left hand side, put the spacer (small diameter in fairing) between
the lower cowl and frame and bolt in place.
