41. If you are planning to use a tuned pipe or canister now is the time to
install it.. You will need to remove the covering, center stringer and
parts of 2 formers to open the pipe tunnel. Seal the edges of the
covering to the edges of the pipe tunnel and paint a thin coat of
alcohol thinned epoxy to seal the wood in the tunnel.
42. I have had great success using the Dave Brown Products tuned pipe
mount.
With the carbon pipe, heat is not an issue and you can secure
the pipe directly to the mount with a nylon cable tie. Using an
aluminum pipe, you must slide some silicon fuel tubing over the cable
tie to prevent the heat from melting it. You will also need to use a
piece of silicon tubing between the pipe and mount to insulate the
mount from the heat.
My pipe mount technique is very easy and involves very little hassle.
First cut a piece of 1/64 ply to fit the width of the pipe tunnel floor, 2
inches wide. Next cut a piece of 1/4 inch light ply into a 1 inch by 2
inch piece. Drill a hole in the center of the 1/4 inch ply and mount the
nylon mount to the ply with the wood screw included with the mount.
Place a drop of CA on the threads as you insert it into the hole. Next
glue the 1/4 inch ply plate to the 1/64 ply, centered. Finally glue the
whole assembly to the floor of the pipe tunnel at 3/4 of the length of
the pipe. For the bigger KS 1060 pipe on the DA set-up I glued the
pipe mount to the side of the tunnel for better clearance.
Secure the pipe to the header using the required hardware and to the
