What is the best Catback aftermarket exhaust for the lexus IS F? I've heard that Joe Z is the best, but I want others opinion. Also will removing the resonators on the JOE Z make it sound more deeper and louder? I'm looking for a loud deep sound. No rasp.

Joe-Z / PTS is the most popular, plus I think it's the best priced as well...

As others have stated, Joe Z/ PTS has been long favored here on the forums. It really does have a nice deep sound to it, and many members have enjoyed the car more with it installed. From what I recall, the ISS QES exhaust (discontinued?) was one of the louder exhausts that some F owners have experienced. After hearing it, it is pretty loud, but I prefer it that way. Some other exhausts in the market are Borla, Meisterschaft, ISS QES and DES (not sure if either are still in production), PPE (testing phaste if I'm not mistaken), and HKS. It'll depend on what you want to spend and how much of a deep sounding exhaust you want. Best of luck!

All of the available exhausts are going to put out similar HP gains, the sound will be what sets them apart and from that it will be what you prefer. VtotheJ mad e a compilation video of exhaust/header sounds in this thread below that might help you. Also, there are countless threads talking about all the different exhaust options/sounds if you just search through them.
