Outlaw Catback Or Axle Backs

[Fast_5.0]

Has anyone run the following:

I have the flowmaster outlaw catback exhaust system.
I have Kooks 1 7/8" x 3" headers.
I have Kooks Shorty Off Road X Pipe 3".

I'm considering using just the axle backs with the headers and x pipe. What's your opinion on running this setup?

I don't have mufflers, but from what I hear you get better sound and performance from a catback system.
