Please do! I was speaking to a person from a reputed exhaust shop in Sydney and he mentioned that a resonator delete will only yield about 3-8% in terms of volume and won't make the car 'louder' like I want it but might introduce drone.
He recommended I keep the factory valves and he'll set up a unique quad muffler design that allows for a 20-30% noise reduction when the valves are closed and will be equivalent to a muffler delete when open. He quoted roughly $1-1.2k (AUD) for that job
