RHD is part of the application for all three kits, rather than a detail to assume from a general Mustang listing. Each package uses 3" collectors and includes the connections and adapters to the OEM rear exhaust.
The two Performance-catted kits suit naturally aspirated 5.0-litre engines. The GREEN-catted 1-7/8" package supports forced induction. Compare the actual combinations below and choose around the engine and rear exhaust you plan to use.
