What the AI looks for in Automotive Replacement Exhaust Clamps

Clamp type: Lap-joint band clamp for slip-fit pipes; butt-joint band clamp for pipes that meet end to end; V-band clamp for flanged quick-disconnect joints; U-bolt saddle clamp only for permanent budget repairs. Each type seals a different joint geometry, and the wrong type leaks.
Diameter: Match the clamp's listed size to the measured outside diameter of the outer pipe at the joint. A band clamp has very little take-up range, so a mismatch will not close or will not seal.
Material: Choose 304 stainless for long life; aluminized or zinc-plated only where low cost matters more than reuse. Plated nuts seize and snap when the system is next serviced.
V-band matching: Buy V-band clamps together with their matching flange pair, or confirm the flange profile is compatible. V-band flange profiles differ between makers and will not seal if mismatched.

A band clamp seals better and does not crush the pipe, so the joint can come apart later. A U-bolt is cheaper but effectively permanent.
