Not sure about that. If you look how a GPF works it works by burning soot from heat. The GPF will be as close to the CAT as possible. The further down the exhaust stream the more heat you lose. The GPF filter regens passively so retaining heat is critical. Sometimes the CAT and GPF are intergrated into one can.
