Are after market fuel rails just for looks or are there any that actually provide a performance gain on a midly tuned engine?

what about the Skunk2 Carbon Composite Fuel Rail
The new composite fuel rails are made using proprietary carbon impregnated aerospace thermo-polymer composite. This insulates the fuel from both radiant and conductive heat transfer under the bonnet. Power gains of up to 3 percent. Features a large 0.625 inch internal bore with radius inlets to the injectors which improve flow. This type of radius injector inlet design is not possible with extruded and drilled alu fuel rails. Skunk2 fuel rails can be used with factory fuel lines and regulators.
Suitable for all Honda B, D, K and F series engines as well as Mitsubishi 4G63 Lancer Evo engines.
