2ndary cats, resonator and muffler

Thinking of doing 2ndary cats, resonator and muffler delete with my 2008 bmw 328i? Will it be a good setup?

It will definitely be loud. Probably boomy as hell as well as a large amount of drone. However if you love loud cars then it may be for you. I have a resonator+muffler delete and it does drone some. Think about removing your muffler and 2nd CATS and keep your resonator just to help with the drone.

I want more of a crackle sound, Should i just leaving the 2nd cat in and going with a res delete and muffler delete?

I have everything you listed deleted and matched with larger size piping and an ikon muffler. Its pretty quiet while driving but once you rev it or floor it sounds so mean. So many people are shocked like what the heck you got in there. I have zero drone or else I would've went with a different route. I have a manual and it crackles and backfires all the time.

Does the secondary cat delete improve sound or not really if its paired with a muffler and cat delete?
