delete 2nd cats with PE E90 330i ?

My 2nd cats are making a rattling noise according to my mechanic. Would it cause any errors if I remove my 2nd cats and add a PE?

There are no side effects at all to removing them. There are no O2 sensors after the downpipes.

Have fun! Mine are gone too.

Isnt there a means of reaplacing them with the N55 mid pipes or am I mistaken?

I just had them replaced with stainless steel straight pipe. Im not familiar with the N55 part. I paid next to nothing for the work so Im sure its less than any other part even if its used.

Check my build thread for more pics
