If you pull the codes and you either have none or they don't have to do with emissions I wouldn't really worry about it unless its so rich its smoking. Since you don't have cats its going to smell some what rich.

you could always bring it to a dyno shop and fine out how the car is REALLY running... instead of just assuming its rich


my car smells really rich at an idle, but my wideband says its around 15.5:1 so im not worried about it. I myself have an o/r x pipe
