About a month ago the muffler (and tailpipes)finally rusted thru. I took the truck to the dealership for an estimate almost $450...yikes! So I went to like Midas and a couple of other muffler shops...way pricey IMO. My bro-in-law has a '03 GMC 1500 and a couple of years ago replaced his exhaust system with a cat-back dual pipe system for under $250 that he bought from LMC Truck. So that is what I did also.
I have had it on for about two weeks now, it runs fine and sounds good also. Yesterday I went to the store and when I restarted the truck the "Service Engine Soon" light came on and stayed on steady. I checked the idiots manual and of course it gives two scenarios both ending up with see your dealership and talking emission controls, etc. I'm not much of a mechanic especially on vehicles newer than mid '70's...once I couldn't see the valve covers when I opened the hood I knew better than to try and mess with anything unless I had someone knowledgeable guiding me

With all the computer controls etc on newer vehicles I'm wondering what I should do now? I don't want to ruin something on the engine.

Any thoughts or ideas ould be appreciated

I think your best bet, would be to take it to a parts supply shop and see if they can hook up their little code sensor to tell you what is wrong.

similiar thing happened to my suburban....i took it to auto zone out here, they check that stuff for free.......eneded up being smog stuff
