The coupler and header are such a tight fit in the MCP that you will not need zip ties.

8. For .32 to .40 engines get a 1/4" alloy tube. For .46 to .53 get a 9/32 or a 5/16" tube.

9. Drill a hole in the center of the bottom of the can for your stinger. Make sure the stinger is a tight fit in the hole.

10. The following set is done with a full size tube. Do not cut the stinger to length yet. Sand the stinger with 320 grit to give the JB weld a surface to grab. Mark a line in the singer 1" from one end of the tube.

11. Mix some JB weld. Put it on the line you marked on the stinger pipe. Just a little bit not too much.

12. Slide the long end of the stinger tube through the MCP and pull it out the hole in the bottom until you see the line you marked. This put a fillet of JB weld inside.

13. Put some JB weld on the bottom of the can and form a fillet for the stinger.

14. Eyeball the stinger about 100 time until you are sure its aligned. Set the pipe stinger up on your bench over night.

15. 24 Hours later cut the stinger to 1" (or whatever size you like). If some JB weld from the inside rain into the stinger tube run a drill bit through to clear the opening.

16. Mount the header on your engine, use a piece of couplet to join the pipes, zip tie the joints and your done!

This is not an original idea. Its a combination if several diffrent MCP designs that I have seen here on RCU into one that works and looks good.
