Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

POST 1 / ORIGINAL POSTEROriginal post

i have a 996 with headers + 200 cat cells with the pse. i noticed that everytime i start my car it smells of fumes, it never did that before. When i drive the car there is a noise from the rear passenger side, just sounds like a muffler issue. I also get the CEL saying aging sensor rear back2. I thought it was an exhaust leak but since a had an issue with myold muffler can the pse be defective again ? or is it the 200 cat cell? why the smell at startup ? when the car runs cold the exhaust note is terrible, any ideas of what i should look at first before i get rid of all this bs and go back to stock cats headers and pse. thank you for the time.

I guess you meant Exhaust Smell and not Exhaust Sell. How old are the mufflers and cats?
