TORQUE SPECIFICATIONS
The 2.5L exhaust system consists of
- an exhaust downpipe.
- an exhaust intermediate pipe.
- a catalyst monitor sensor mounted to the underbody catalytic converter.
- an underbody catalytic converter and muffler assembly that is a 1-piece design (OEM) and a 2-piece design for service.
- a muffler brackets with isolators bolted to the body.
- a resonator tailpipe assembly.
The 3.0L exhaust system consists of
- a one-piece LH catalytic converter manifold.
- a RH exhaust manifold mounted catalytic converter.
- an exhaust Y-pipe.
- an underbody catalytic converter and muffler assembly that is a 1-piece design (OEM) and a 2-piece design for service.
- muffler brackets with isolators bolted to the body.
- a resonator tailpipe assembly.
The 2.5L Hybrid exhaust system consists of
- a one-piece catalytic converter manifold.
- an intermediate pipe.
- an underbody catalytic converter and muffler assembly that is a 1-piece design (OEM) and a 2-piece design for service.
- muffler brackets with isolators bolted to the body.
- a resonator tailpipe assembly.
The exhaust system provides an exit for exhaust gases and reduces engine noise by passing exhaust gases through the catalytic converters, a muffler assembly and resonator. Rubber exhaust hanger insulators attach the exhaust system to the mounting hooks.
