A friend of mine owns a 99 GT with 105K miles on it. Approximately 3 weeks ago he had a new mufflers and an X-Pipe installed (without cats). Just the other day his service engine light came on and hasn't gone off since. Could this be due the the new exhaust components? What can be done to correct this?

The o/r x-pipe is mostly likely causing the light. Just buy some MIL eliminators for a couple of bucks and this should clear it. The light is causing no harm to your engine. It just letting you know that the CATS are not working correctly.
