If you have an exhaust pipe with a worn flex connection, Jones Universal Spherical Joints enable you to replace the leaky connection point rather than your entire exhaust pipe. Simply clamp-on or weld the stainless steel joint connector to your existing exhaust system. Jones spherical joints reduce back pressure, include spring bolts, and are available in a variety of pipe size diameters, so you can choose one that's right for your exhaust needs.
