This tip is a solid tube that sticks out the back of the muffler but if you use a small flashlight and look inside you can see that after an inch or two into the muffler it is perforated. There is a seam running along the bottom of it like a weld, that on my bike at least, looked like it had not been closed all the way-that is the two edges of the seam did not meet up all way. My reasoning was that if I used the epoxy to close that small gap that maybe the chirp would stop. The stuff is kinda thick however and I ended up spreading it like peanut butter all over the bottom of the perforated part of the tube. This filled in the perforated holes as well as the open seam that ran along the bottom of the pipe. I only used the stuff along the section of the pipe that was perforated - not on the solid part near the exhaust exit. Because of this you cannot see the stuff from the back of the bike unless you look inside the exhaust exit with a flashlight. I also sprayed some flat black high heat paint (for use on wood stoves) into the pipe to hide the grey epoxy inside. I did not use too much of the epoxy, only enough to fill in the holes and the seam but not enough to make the diameter of the tube any smaller. Also I ran it all the way along the tube till it ends about 7-8 inches inside the muffler. Hope this helps Drew Nielsen
