My rear muffler rusted...

My rear muffler rusted out and fell off of my car

Mechanic's Assistant: How many miles are on the car? How has your MPG been lately?

166k not much different MPG

Mechanic's Assistant: What is the model/year of your Infiniti?

02 qx4

Mechanic's Assistant: Are you fixing your QX4 yourself? What have you tried so far?

I will be, Just not 100% sure what parts I need I know i need the rear muffler, but should I replace all the attaching hardware? Should I replace the whole muffler system at once?

Mechanic's Assistant: Anything else you want the mechanic to know before I connect you?

I do have an O2 sensor code being thrown, but that's of less concern than the muffler situation

Good afternoon since the vehicle has higher mileage i recommend you replace the exhaust system from the catalytic converters back , leave the converters on because if those are still good leave them on so they wont give you no issues and you dont need the extra cost , you will need to order what we call a cat back exhaust you should be able to replace it with new clamps , gaskets and bolts also . I hope this helps please dont forget to provide positive feedback/star rating for the help provided thank you
