    Fireballs from exhaust...

    so i was cruising last nite with some biker frends, and a couple of them said they saw fire shooting out of my exhaust a couple times when i was WOT. this just means im running rich rite? i recently put in some e36 m3 17.5lb injectors, and my gas mileage has been the shits, so im assuming im running rich. BTW i have a JC chip if that makes any difference...

    I find that unlikely. Cats/resonators usually quench any fire long before it gets to the muffler and out the tailpipe.

      I've seen evo 8s do that on the track, I think they were stock.

          Its posible ive seen cat(s) do this when there crapining out. Well in your case that rich mixture could have caused it to go bad.

              I'm not saying they are lying. Just that its unlikely.

              Do you have shiny exhuast tips? perhaps they caught a glint of reflection?

                    An overly rich mixture can also melt the core of the cat.

                              aha. i was unaware. i figured i would get a lil worse mileage, but im talkin like 15mpg in the city...maybe my foot just got heavier.
