The invention recites an exhaust pipe clamp for clamping at least two pipes. The clamp includes a band formed to at least partially surround each of the two pipes, the band defining an internal volume. A reaction block is interconnected with the band and disposed substantially within the internal volume. The exhaust clamp also includes a clamping member operable to reduce the internal volume of the band.

What is claimed is: 1. An exhaust pipe clamp for clamping at least two pipes, the clamp comprising: a band formed to at least partially surround each of the two pipes, the band defining an internal volume; a first reaction block and a second reaction block, the first and second reaction blocks interconnected with the band and disposed substantially within the internal volume; and a clamping member operable to reduce the internal volume of the band. 2. The exhaust pipe clamp of claim 1, wherein the band and reaction block cooperate to substantially surround and separate the pipes. 3. The exhaust pipe clamp of claim 1, wherein the first reaction block and the second reaction block cooperate such that each block applies a force that is substantially perpendicular to the clamping member to at least one of the at least two pipes. 4. The exhaust pipe clamp of claim 1, wherein each reaction block includes an arcuate surface and an angled surface opposite the arcuate surface, the angled surfaces in contact with one another and the arcuate surfaces cooperating with the band to define lobes, each lobe adapted to substantially surround one of the pipes, wherein operation of the clamping member moves the reaction blocks to reduce the internal volume. 5. The exhaust pipe clamp of claim 1, wherein each reaction block includes a flat top surface, the top surfaces engaging one another in a clamped position to prevent further movement of the clamp. 6. The exhaust pipe clamp of claim 1, wherein the clamping member comprises a bolt. 7. The exhaust pipe clamp of claim 1, wherein the band is formed as one continuous piece. 8. The exhaust pipe clamp of claim 1, wherein the band is figure-eight shaped. 9. An exhaust system comprising: a first outside pipe; a second outside pipe spaced a distance from the first pipe; a first inside pipe, a portion of which is at least partially disposed within the first outside pipe; a second inside pipe, a portion of which is at least partially disposed within the second outside pipe; and a pipe clamp including a band at least partially surrounding a portion of the first and second outside pipes, a first reaction block and a second reaction block, the first and second reaction blocks interconnected with the band and disposed between the first and second outside pipes, and a clamping member operable to move the first and second outside pipes into substantial sealing contact with the first and second inside pipes respectively. 10. The exhaust system of claim 9, wherein the band and reaction block substantially surround and separate the outside pipes. 11. The exhaust system of claim 9, wherein the first reaction block and the second reaction block cooperate such that each block applies a force that is substantially perpendicular to the clamping member to at least one of the first outside pipe and the second outside pipe. 12. The exhaust system of claim 9, wherein each reaction block includes an arcuate surface and an angled surface opposite the arcuate surface, the angled surfaces in contact with one another and the arcuate surfaces cooperating with the band to substantially define two lobes, wherein operation of the clamping member moves the reaction blocks and moves a portion of each outside pipe into sealing contact with the respective inside pipes. 13. The exhaust system of claim 9, wherein each reaction block includes a flat top surface, the top surfaces engaging one another in a clamped position to prevent further movement of the clamp. 14. The exhaust system of claim 9, wherein the clamping member comprises a bolt. 15. The exhaust system of claim 9, wherein the band is formed as one continuous piece. 16. The exhaust system of claim 9, wherein the band is figure-eight shaped. 17. A pipe clamp operable to provide a joint between first and second outside pipes and first and second inside pipes, the clamp comprising: a band formed to define a partial figure-eight shape at least partially surrounding the first and second outside pipes adjacent the joint; a first reaction block having an arcuate surface; a second reaction block having an arcuate surface, the first and second reaction blocks positioned within the band, the band and arcuate surfaces together substantially defining two arcuate lobes, each lobe having a size and substantially surrounding one of the first and second outside pipes adjacent the joint; and a clamping member defining a clamping axis and operable to move the first reaction block and the second reaction block perpendicular to the clamping axis and toward the first and second outside pipes respectively to reduce the size of the two arcuate lobes and to move the first and second outside pipes into substantial sealing contact with the first and second inside pipes respectively. 18. The pipe clamp of claim 17, wherein each reaction block includes an angled surface, the angled surfaces in contact with one another such that operation of the clamping member moves the reaction blocks to partially reduce the size of the two arcuate lobes. 19. The pipe clamp of claim 17, wherein each reaction block includes a flat top surface, the top surfaces engaging one another in a clamped position to prevent further movement of the clamp. 20. The pipe clamp of claim 17, wherein the clamping member comprises a bolt.
