I am about to install my AA catless headers. I am currently running the AA Gen2 axel back (small muffler and drone control chamber), custom mid pipe and resonator, secondary cat delete and AA tune. Current sound is great. Hoping it will be a bit more aggressive after headers are in.

It may be a bit much deleting all those components. You may want to consider some that will control the noise/sound/drone a bit to avoid excessive rice sound.

I can advise more after my headers go in. Just my 2cents.
