Have a random exhaust smell in cabin. Only notice it when car is stopped after it has been after being driven for a while. At lights or intersection cues. Does not happen that much in Tamworth
I chased the problem some time ago and installed the carbon activated cabin filter. Then I thought it might be my provent venting so I replaced the cap rubber o-ring.
The exhaust flex pipe has been mentioned but I have never seen a picture of what they are talking about.
After researching on RockAuto it looks as though both exhaust headers have a section of flex pipe in them. No listing of this part just complete header. Has anyone actually replaced just the flex pipe ??
