I don't see a reason at to your exhaust to causing your check engine light to come on. I would take it back to where you had it installed. The only thing I could think of is that they might have bumped or messed up your O2 sensor on your cat.[IMG]i/expressions/face-icon-small-confused.gif[/IMG]

Did you fill up on gas and not hear the "click" noise?

I'm pretty sure it's not your exhaust.
You might wanna try resetting your ECU.
1. Disconnect the black terminal for 5-10 minutes...
2. Connect it back and turn on your car. Let it idle (do not press the gas) for 10-15 minutes.

Let us know if this does the trick...
