1. A method of making a pollution control device, said method comprising: forming a self-supporting insulating end cone comprising a single, continuous piece of non-intumescent insulating material, the insulating material comprising inorganic fibers and a binder, and the insulating end cone having a three dimensional cone shape, where said forming comprises shaping non-intumescent insulating material into the three dimensional cone shape using a mold; anddisposing the insulating end cone within a gap between inner and outer end cone housings of the pollution control device,wherein the insulating end cone is dimensioned so as to fill the gap between the end cone housings, such that there is no air space between the insulating end cone and either end cone housing, the insulating end cone maintains its three dimensional cone shape under the force of gravity, when placed on a level surface prior to said disposing, and the insulating end cone exhibits a resiliency value of greater than about 35 percent when evaluated using the Resiliency Test Method. 2. The method according to claim 1, wherein prior to said disposing step, the single, continuous piece of non-intumescent insulating material is compressed by a factor of 1 to 10. 3. The method according to claim 2, wherein the single, continuous piece of non-intumescent insulating material is physically compressed by resin bonding. 4. The method according to claim 3, wherein the binder comprises an organic binder. 5. The insulating end cone liner according to claim 1, wherein said insulating end cone liner exhibits a resiliency value in the range of from about 35 percent up to about 97 percent when evaluated using the Resiliency Test Method. 6. A method of making a self-supporting insulating end cone having a three dimensional cone shape, said method comprising: forming a flexible and self-supporting insulating end cone comprising a single, continuous piece of resilient and compressible non-intumescent insulating material, the insulating material comprising inorganic fibers and a binder, and the insulating end cone having a three dimensional cone shape, where said forming comprises shaping non-intumescent insulating material into the three dimensional cone shape using a mold,wherein the insulating end cone is dimensioned so as to fill a gap between an inner and outer end cone housing of a pollution control device, such that there is no air space between the insulating end cone and either end cone housing, the insulating end cone maintains its three dimensional cone shape under the force of gravity, when placed unsupported on a level surface, and the insulating end cone exhibits a resiliency value of greater than about 35 percent when evaluated using the Resiliency Test Method. 7. The method according to claim 6, wherein the non-intumescent insulating material is compressible by a factor of 1 to 10. 8. The method according to claim 6, wherein the binder comprises an organic binder. 9. The method according to claim 8, wherein the insulating material further comprises an inorganic filler. 10. The method according to claim 8, wherein the insulating material further comprises from about 60 to about 98 dry weight percent inorganic fiber and from about 2 to about 25 dry weight percent binder. 11. The method according to claim 6, wherein the insulating end cone has an uncompressed wall thickness of from about 0.5 to about 15 mm. 12. The method according to claim 6, wherein the binder comprises one or more inorganic binders. 13. The method according to claim 6, wherein the insulating end cone has an uncompressed wall thickness of from about 0.5 to about 15 mm. 14. The method according to claim 6, wherein the insulating material comprises essentially shot-free ceramic fibers that contain less than 5 percent by weight of shot or non-fibrous particulate material. 15. The method according to claim 14, wherein the essentially shot-free ceramic fibers are selected from the group consisting of alumina-boria-silica fibers, alumina-silica fibers, alumina-phosphorus pentoxide fibers, zirconia-silica fibers, zirconia-alumina fibers, and alumina fibers. 16. The method according to claim 6, wherein the insulating material comprises essentially shot-free ceramic fibers that contain less than 1 percent by weight of shot or non-fibrous particulate material. 17. The method according to claim 6, wherein the insulating end cone is compressed to a mount density of about 0.05 and 0.60 grams per cubic centimeter such that the insulating material is able to repeatedly undergo a reduction in thickness while hot and spring back to substantially its original thickness when cooled to room temperature. 18. The method according to claim 6, wherein insulating material has a density in the range of 0.05 to 0.30 grams per cubic centimeter and is able to repeatedly undergo a reduction in thickness while hot and spring back to substantially its original thickness when cooled. 19. The method according to claim 6, wherein the inorganic fibers comprise at least one of polycrystalline alumina fiber and refractory ceramic fiber. 20. The method according to claim 6, wherein the organic binder is selected from the group consisting of emulsions of organic polymers, elastomers in latex form, natural rubber lattices, styrene-butadiene lattices, butadiene acrylonitrile lattices, lattices of acrylate, methacrylate polymers and copolymers, thermoplastic polymers and polymer resins, natural rubber, styrene-butadiene rubber, other elastomeric polymer resins, acrylic latex and polyvinyl acetate.
