Default question about exhaust...

I'm installing a magnaflow cat
back exhaust tomorrow and need some clarification regarding the ECU. Is it important that I reset the ECU after the instal and if so, is resetting it just a matter of disconnecting the battery? Or will the ECU 'learn' quickly on it's own without a reset and adjust for the new exhaust? If so, how long does it take to learn and will I notice a power differnece in the meantime?

Thanks in advance for your help!

Default Difference is noticeable immediately.

The biggest gain is most noticeable right out of the box. Not sure if there's more hp that "comes on" after the ECU adapts, as I didn't dyno later on.

Trust me...you'll feel the difference immediately.
