an exhaust clamp comprising a second circular section and a second bolt section, where the second bolt section has two parts which are secured to the second circular section at two separate locations which are not in contact with each other, the exhaust clamp being connected to the header clamp by a cable; the cable having eyelets at both ends; a cylindrical sleeve, movably located along the axis of the cable; and the eyelet accommodating a bolt used for attaching the clamp. ### Claim 2 (depends on 1) The system of claim 1, further comprising: the eyelets being swaged eyelets. ### Claim 3 (depends on 1) The system of claim 1, further comprising: the eyelets being swageless eyelets. ### Claim 4 (depends on 1) The system of claim 1, further comprising: the eyelet having a neck-length and head-width conforming to predetermined requirements regarding a distance between the bolt and a surface of the clamp. ### Claim 5 (depends on 1) The system of claim 1, further comprising: the cylindrical sleeve having a surface usable for identifying a specific manufacturer of the system. ### Claim 6 (depends on 1) The system of claim 1, further comprising: a first bolt, having a threaded portion and a non-threaded portion, the first bolt passing through both portions of the first bolt section; and a second bolt, having a threaded portion and a non-threaded portion, the second bolt passing through both portions of the second bolt section. ### Claim 7 (depends on 6) The system of claim 6, further comprising: the respective eyelets being attached to the respective clamps by having the respective bolts pass through the respective eyelets. ### Claim 8 (depends on 7) The system of claim 7, further comprising: the respective eyelets being movable along the axis of the respective bolts. ### Claim 9 (depends on 6) The system of claim 6, further comprising: the first and second bolts being slightly curved at one end. ### Claim 10 (depends on 6) The system of claim 6, further comprising: the header clamp being a different diameter than the exhaust clamp. ### Claim 11 (depends on 1) The system of claim 1, further comprising: during use, a separation force applied to the cable occurs in a direction parallel to a center axis of the respective clamps. ### Claim 12 (depends on 1) The system of claim 1, further comprising: the system functioning within a high temperature environment, specifically the temperatures found underneath hot rod vehicles and the temperatures found near to a collector and an exhaust of a hot rod vehicle. ### Claim 13 (depends on 12) The system of claim 12, further comprising: the cylindrical sleeve has advertising, promotional, or other information imprinted thereupon, wherein the imprinting remains readable including at high temperature. ### Claim 14 (depends on 1) The system of claim 1, further comprising: the cylindrical sleeve has a non-slit unibody construction. ### Claim 15 (depends on 1) The system of claim 1, further comprising: the cylindrical sleeve is made of a specific color or dimension in order to quickly and visibly signify information to a user. ### Claim 16 (depends on 1) The system of claim 1, further comprising: the cables and clamps each respectively having a variety of sizes.
