If the mongoose has the same fittings as the nissan front pipe then yes it will fit as i have the standard front pipe, which will mate up with the 3" outlet.
My decat pipe has replaced the standard cat, So i imagine that the front pipe will mate up with the goose cat part.
My zorst at the minute is this:
Nissan turbo outlet,
Nissan Front pipe,
De-cat pipe 3 1/2",
5-Zigen mid section 2 1/2",
Modded mongoose tail section.
