Hey,

If you have the factory exhaust manifold, this is normal. The factory manifold is very long for a 4 cylinder (even long by modern car standards) and as such there's a lot of heat shield(ing) to expand and contract.
You won't hear this on other cars as much because their manifolds are a lot more compact compared in design to our cars.
Source: used to own a S13 240SX, with a factory manifold comparable in length (overall) to the FRS/BRZ. The car would take forever when cooling down for the noises to go away.
