Installation Note

WARNING: This page is about a different car, the 2007 Mazda B2300. However, it is still accessible from the selected car via links, so may be relevant.

CAUTION:

Do not tighten the exhaust system fasteners until all components are assembled and aligned, making sure to tighten all fasteners beginning at the front of the vehicle.

CAUTION:

Do not use oil or grease-based lubricants on the isolators. These lubricants may cause deterioration of the rubber. This can lead to separation of the isolator from the exhaust hanger bracket during vehicle operation.

NOTE:

Clean the mating surface of the exhaust manifold outlet flare and the exhaust down pipe inlet flare. Make sure not to damage the exhaust manifold outlet flare or the studs.

NOTE:

Clean the mating surface of the exhaust down-pipe or the catalytic converter and the muffler and tailpipe assembly. Make sure not to damage the exhaust down pipe or the catalytic converter and the muffler and tailpipe assembly mating surfaces.

NOTE:

Make sure to apply anti-seize lubricant to the threads of the sensors before installation.

If removed, install the HO2S and catalyst monitor sensor.
