Generally, people will pull the fuse on the factory system to allow it to remain open all of the time. The
Flowmaster American Thunder kit is an entire Cat-back system. Installing this
Flowmaster system will disable the active dual mode function. We provide plugs to cap off the stock actuator lines. There is no need to pull any fuses.
