I just replaced catalytic converter and tail pipe on 2.2 Subaru Legacy Auto 1994. After three days, I noticed that the inside of the new tail pipe was covered with black soot, indicating (to me) that the engine was running too rich. I understand that the computer is supposed to adjust the mixture.
Any suggestions will be appreciated
Thanks
Now you know WHY it needed a new convertor! Better get that straightened out QUICK before you melt down the new one...
Um, I might be stating the obvious here but I hope you don't think it's supposed to be grey inside the tailpipe?

I would like to express my profound gratitude for the most useful responses (2) I received following my request for suggestions.
I suppose that I am guilty of lack of clarity in my request. I shall therefore rephrase:
will be appreciated.
I am delighted to be **alarmed** by the necessary promptness in correcting this "mixture" problem and delighted to be asked my preference in colours for the exhaust pipe.
I do express my thanks for the extreme concern previously stated.
