Abstract
A Y-shaped, clam shell type coupling device for use in automotive vehicle exhaust systems to couple two exhaust pipes that are connected to an engine manifold to a single exhaust pipe that is connected to a catalytic converter or exhaust silencing device. The clam shell type coupling comprises a pair of mirror image half shells which combine around the exhaust pipes in fluid tight fashion to form two generally tubular intersecting chambers. One of the chambers may provide a direct pathway from one of the manifold exhaust pipes to the single exhaust pipe.
