It's dump , then front pipe then to the catalic converter, running to the resinator ,then to the muffler.
A resonator is optional, you would be much better off running a 3" pipe from the cat back to the muffler and replacing the cat with a high flow 3" jobby, the dump pipe you have chosen there is good but have you searched for one here? Batml? has a good priced one and has the big cats as well.
