A V-band is the joint you want anywhere the exhaust has to come apart again, because it seals on a machined face rather than by crushing a pipe. Undo one clamp and the section lifts away, and it goes back together sealed without a new gasket.

• Suits 3 in. exhaust tubing.
• Includes two stainless steel weld-on flanges.
• Clamps the flange pair together for a leak-free, separable joint.
