Default Catback B&B Install Question

Installation instructions says to "disconnect the negative battery terminal...may allow the computer to 'clear' its memory during installation".

What will this accomplish? Is it a necessary step to take?

Installed a few catback exhausts - never disconnected the battery. This must be a CYA thing for product liability.

I used to write for Mitchell Repair Manuals. 99% of every repair or remove/install procedure we wrote began with the phrase "Disconnect the Battery."


In cases where the system being worked on is non electrical, it's more of a CYA and a method of ensuring the engine does not start inadvertantly.

Maybe it's a way to force the PCM to do idle re-learn or something. Can't imagine why they would say that unless it's CYA.

Sounds like a waste of time to me. If you receive an electric shock from installing an "exhaust" at the "rear" of a car, then you got bigger problems than the battery.
