Is the exhaust all that restricted on a yaris? And if so, is the manifold that big of a bottleneck?

i think these guys are talking about making a manifold for a turbo charged set-up. there are plenty of non-turbo manifolds available.
the manifold is slightly restrictive, like most stock manifolds.
