About time of installation this will depend on how you want to control the muffler valves.
FOB Remote. The easiest and quickest way is to use the FOB remote to control the valves, this means that you don't need to make any holes anywhere to mount a switch on the dashboard area and this also means that you don't need to get electrical wiring from the dashboard area all the way to the engine bay compartment. Approx time of installation 3 Hours.
The valves are closed by default, when starting the car the valves will be in the closed position.
Dashboard mounted switch. The muffler valves can also be controlled with a simple on/off switch that can be installed pretty much anywhere where it makes sense to you, that can be on the trim underneath the handbrake, the center console, on the steering wheel trim, on the side of the seat etc... in other words where you want it to be. This would be type of on/off switch that you will control by either putting the switch to OFF or ON mode. This installation requires electrical wiring to be routed from the dashboard area to the engine bay, for a clean job the necessary trims will have to be removed so that no wires can be seen. Approx time of installation 3-4 Hours for a complete installation of switch kit and mufflers
