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.
When you choose to install the FOB Remote kit the exhaust system will be on the open valve by default when you start up the car, you must press the remote to shut the valves.
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
OEM Porsche exhaust switch. Porsche does have a switch that has an exhaust pipe logo on it, this switch will fit in one empty slot on your radio surround trim or on the lower trim of the center console, if you have an empty spot available this switch will give you a factory look, the part number is 996.613.987.10A05 (left side of the dash installation) or 996.613.988.10A05 (right side of the dash installation) this switch will run you approx $30 from your local Porsche dealer. This installation requires electrical wiring to be routed from the dashboard area to the engine bay, in addition a relay needs to be added to make the factory porsche switch work. We don't offer support for the factory exhaust switch please talk to your qualified technician for this type of installation.
