They are not allowed to remove cats due to emmision requirement.
Good to hear! Keep driving and it will get better--that's what I've noticed. Yep, my shop told me the same thing but I am going to bring it to a performance shop to do it for me and do the tune myself. I will get an inspection before I do the test pipes so I have at least a year to play with it.
