Read the WELCOME ALL BMWFANATICS post.
Has anyone done a de-cat on their 6cly E90 yet?

it probably has 23 cats so its going to be pricy 
i would be more worried about if the engine will accept a decat... you definitely need to find a place that has done it before

Done the research, the exhaust manifold is split in two pieces. One manifold for the first three cylinders and one for the last three. Each manifold has a cat attached to it so there are two cat converters. There are some senors that will need to be overridden with software
Okay just spoke to Alister at Xcede, there are four cats on the car and they have done a few cars already.
R8000
Remove cats
Make new exhaust manifold
run new piping
and finally update software.

do the boxes really flow enough with a decat and branch? Surely you would get more if you changed the boxes also?
if they flow that well then thats awesome when make noise if you dont have to...
