ABSTRACT:
A spring connecting or adapted to connect the cut-off ends of an exhaust pipe, particularly of a tractor or the like, after it has been cut in two. The spring is preferably welded at each end to a corresponding end of the exhaust pipe cut in two, or, when an adapter or flared connector pipe is used at each end, the adapter or flared connector pipe is so welded. A flexible liner hose may be used and may have each adapter embedded in it. Each adapter may have a notch or V-cut in it at each cut-off end of the exhaust pipe.
