So I have the Flashpaq and the aFe exhaust. Nothing installed yet. It may be a week or two until I install the exhaust. I am wondering how I should proceed from here.

1) Install the Flashpaq now and then install the new exhaust later.

2) Wait until I install the exhaust and then install the Flashpaq.

If I do #1, would I have to uninstall the Flashpaq and then re-install it again after the new exhaust is installed?
