Not a particularly elegant solution, but I have a set of shell valley side pipes and they began to rattle on account of something coming loose within the inner baffled system. I drilled about 8 1/4" holes along the bottom of the pipe where they would not be visible, and pumped the pipe with an entire large tube of high-temp silicone. Let it sit of over a week. This did not resolve the mechanical source of the rattle, but it certainly reduced it by 70-80%.
