Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Exhaust System: Description
The exhaust system (Fig 1 ) or (Fig 2 ) consists of two front close coupled catalytic converters. Both converters attach directly to the exhaust manifold using a V-Band clamp. The exhaust down pipes exit the converters and connect into the front resonator. The front resonator, intermediate pipe, and muffler are one single module. The rear resonator and tailpipe connect to the muffler outlet. The 300M Special has both a left and right rear resonator. The upstream oxygen sensors are located in each exhaust manifold. The downstream oxygen sensors are located at the rear of each catalytic converter.
