Test pipe install question

[dutchbuffalo]

Do I need to undo the negative battery terminal before installing a test pipe or is it not necessary ? Thanks.

I have put a few on for Ken and never disconnected the battery.

Not necessary. It may adjust things slightly, but its hard to say. Usually exhaust mods don't need a neg. terminal disconnect.

i'd say no. not enough of a change in parameters to need a reset.
