Check engine light?
I recently had the greddy sp2 exhaust installed on my car. Runs great, sounds great. The next morning the check engine light came on. I thought it had something to do with the way the new flow of air was being picked up by the computer. I un-hooked the battery, waited about 20 minutes, turned the car back on. Wa-la. Light went away, or so I thought. It has been about a week 1/2 and the light came back on this morning as soon as I started the car. Any suggestions other than take it to the dealer?

Find someone with a CAN-compatible OBDII scanner and read the DTC. Only way to be sure what is causing the error. You can purchase such a scanner for about $60 if you want to buy one.
Having said that, if your new exhaust system does not accommodate the OEM O2 sensors, that could be the problem.
