idunnoYou could for safe measure. Wouldn't hurt to try. Anything have to do with your engine and sensors, I would.

you don't have to. if a CEL comes on though then you might want to.

but as already mentioned...it definately doesn't hurt at all to do it..it's just not needed.

Resetting the ECU will improve the gains much more than driving with the ECU set up for a stock exhaust system. You'll notice a huge difference in power the first time you go driving after the ECU reset.

basically, yeah. The ecu has settings that adjust themselves to the way you drive and the systems that are on your car.
