I'm thinking as an alternative, to remove the pre cats and leave the back box OEM

I definitely have no plans to do anything else right now. To put things in perspective, while I owned 3 E46 M3 Convertibles in the past, this is the first time I have ever modified a car. So I'm pretty conservative compared to many people on these boards.

Unfortunately I have never heard a cat delete so it's hard for me to give you feedback on it. Sorry I couldn't be more helpful...
Thanks man, I think I will start with just the test pipes, then if need be change the rear box
