... isn't that a sign of running too richly?

Can you post a pic of yours?

I think that's normal, as long as it isn't a lot. I always have a bit of "soot" on the bottom lip of my tips after my 30 mile round trip commute to work each day. I just wipe them down every other day or so long with my chromies. I had the same thing on my Honda. I think most modern engines are set slightly on the rich side for safety's sake.

i have had soot in the bottom of the pipes of every car ive owned....even the 98 HP saturn
i have soot also on my fx35 exhaust pipes in the same location as yours. thought it was odd when i noticed it a few weeks ago, but completely forgot until i saw this post
depends on how much you sit, at idle, with the motor running....

im sure you 'blow it out' every so often, but still carbon deposits will accumilate when your sitting idel, for periods of time (and the a/c consendation only makes it worse)

This IS Kenny you're talkin' about, ya know. If it wasn't for CA traffic, I doubt that his FX would ever be at idle except when shifting to/from park.

FWIW, I've got the same soot, and yes, I "blow it out" nearly every day...gotta keep the pipes clean :D
Unfortunately, that's normal. Unless it turns the exhaust tips REALLY black and/or makes the rear hatch dirty with exhaust soot, I would guess it's not running overly rich. Your gas mileage would probably be abnormally low if it was that rich as well.
If you are going to represent jersey, then you have to change your location. Nice plates though. :) Don't worry about the soot. That's normal. All it indicates is that there is a little incomplete combustion. Meaning that your air to fuel mixture is a little rich w/ more fuel than air.

Is the soot something to worry about? I've seen it on almost every car I've had.
I wouldn't worry about it. Pretty much every car will turn the inside of the exhaust black sooner or later.
Re the avatar and my location - long story short - born and raised on Long Island, lived in northern NJ (Bergen/Hudson) for the past 8+ years, moved to SoCal in February... just trying to stay true to my roots!

Driving around LA with my NJ plates for a few months after I moved really stood out in a nice way (LOL) but then had to re-reg and my FX is LA-purchased so I will have Cali plates on those from the get-go.
