Pros and Cons of...?

Pros and cons of cutting the secondary cats off a e90 325i?

Please be as detailed as possible. For example; if power is gained, would it be low end or high end? Also, please post both pros and cons.

Tried searching, didn't come up with the exact answer I was looking for.

Thanks for any help

Nah, the resonator is different. If you looked under your car when you were getting your resonator cut off. You would have seen two smaller cats in front of the resonator. The resonator is only for sound while your cats are for emissions. But, you have 2 sets of cats, so taking off one would give you a good power increase and you still wouldn't be destroying the environment.
