Exhaust System: Description and Operation

The exhaust system incorporates (in order from front to rear)an exhaust manifold rear pipe (also called a Y pipe), catalytic converter, resonator, intermediate pipe, mufflers and tail pipes. The exhaust crossover pipe attaches to the front and rear exhaust manifolds. A joint coupling, using a round graphite impregnated seal, connects the rear exhaust manifold pipe to the inlet of the catalytic converter. The rear exhaust manifold pipe or Y pipe contains a flex joint. This joint replaces the exhaust springs commonly used with bolts that attach the rear exhaust pipe to the manifold and crossover pipe. The intermediate pipe assembly is welded to the converter outlet.
