removing cat converter

[oomph]

will removing the cat also remove "backpressure" which may result in poorer low end torque ?

Does the E60 have 2 cats or just one? If the first one is with the header, where is the second one located?

2 cats....2nd one is between headers n muffler. removing cats...is a serious decision. it will make ur car very loud. but ur petrol consumption will go down at least 1.5l/100km. throttle response is almost instantaneous though. at 1700rpm..u will hear the raspy sound.

If I remove the 2nd cat, would it be able to pass emission test?

Removing the post cats will be louder by abt 20-30% more. I think its as good as another mod on the rear muffler.
