RE: check engine light after exhaust change
What did you change? A lot of times an exhaust change screws with the oxygen sensor(s). Our trucks typically have one before and one after the cat. It looks for a difference between the two readings to be in a set range. You put a high-flow exhaust on or junk the cat, you often will put the difference out of the range and trigger a code.

when you say that you changed your exaust system.. did you change mufflers, cat, headers and everything?

I'm going with snafu on this one. . .I changed out the exhaust on my taco and had the same thing. . .drove it around for a bit and it went away. it's prolly just your O2 sensor.
if it doesnt clear out after a while of driveing the it could be your O2 sensor did go out
