#11875 is an NPP axle-back system. These aren't difficult to install at all. Really, the hardest part is just the contorting of the factory mufflers and pipes to get them out from under the car. A lift or a good set of ramps/Wheel Cribs or similar helps immensely.
You'll remove the harness clips from the two NPP valves and the two AFM valves, remove the factory muffler assemblies, unbolt the AFM and NPP valves, and transfer them over. After that, the pipes and the mufflers go right back on, only this is far easier due to the split design.
Overall, you're probably looking at a few hours with basic tools.
