Default Newbie here with exhaust question

I just purchased a 99 Z-28. All stock with a slowmaster added. First mods I plan on doing are the freebie mods along with a slp lid and k&n filter. As for exhaust I don't mind the sound of the flowmaster. Just that what I see is it's restrictive. I am down to one of three options. Have to run cats so not looking to run headers anytime soon. So hoping you guys can help. Option 1 is switch to a slp loudmouth 1. Option 2 dynomax 19418 ultra flow exhaust. Option 3 is just weld in a electric exhaust cut out. Thank you all in advance.....

This is the correct answer. Also, you can get headers and still have cats so don't rule them out for that reason only.
