THE L67 EXHAUST SYSTEMThe exhaust system on the L67 engine incorporates (in order from the front to the rear)
^ An exhaust manifold front pipe
^ A three way oxidation catalytic converter
^ A resonator
^ An intermediate pipe
^ Mufflers
^ Tail pipes
The exhaust manifold front pipe is welded to the catalytic converter therefore, they are serviced as one unit. The exhaust crossover pipe attaches to the front and the rear exhaust manifolds.
All exhaust pipe to exhaust manifold connections are of the ball joint type to allow angular movement for engine roll motion.
