Is it necessary/recommend to reset the ECU (unplug the '-' (negative) battery cable for a few minutes) after installing an exhaust?

I know it is recommended for an intake.

Just want to make sure - although I doubt it would hurt.

 

regardless i would do it, and let my ecu remap all the curves with the exhaust.

 

except for a 2k3 unplugging the - terminal won't reprogram the ecu.

 

I have a 2K3.

 

for 02-3, you don't unplug the battery

Thats weird i have 2000 and i install ingen intake and cat back exhaust and the y-pipe.
i did not reset my ECU ,And the SES light never come on it's been 6 month now no problem.
Is there something wrong with my ECU?

 

Resetting the ECU only clears stored error codes, it does not erase or reset stored operating parameters.

The ECU will immediately learn and adjust for any performance mods you install by looking at MAF (air flow) readings and O2 sensors.

 

i did not reset my ECU either!!

 

how would you reset your ecu without disconnecting your battery. doing it from the inside of the car.
