You can pull the fuse and leave t open all the time. But is always nice to have control of the butterflies so you can go quiet if you want to.
I have my new controller available, the Exhaust Commander Car2u which can be controlled using you universal visor remote. No keyfob remotes needed.
It's available at
www.shop.sunsetorangecreations.com
for $125 plus shipping.
Exhaust Commander Car2U is a great choice for those who want to take full command of their exhaust and don't want to worry about keyfob remotes.
