For a 4L V6 I'd go a 2 1/2 inch full system with 18" resonator... maybe even 2 x resonators. These help with vibration. You'd normally find this for between $250-600 depending on location and bend type.
Oh, and you should fix your air-intake, falcons LOVE being able to breathe more.

Ive got a 2 1/2 lukey cat-back on my 92vp. I put a stock exhaust on to get rego done even tho the other IS legal, It was cheeper to buy a new stock exhaust to pass rego in nsw than it was to get an engineers cert.
