Hello,

I changed the thread, because last one isn't actual

Ok, so I have already bought muffler from 440i to my 430i.

and now .. there are some questions (i don't have a car, im still waiting for import, but I would like to collect all parts )

Now I need to buy M-performance diffuser to F32 - it's not a problem. I will buy this one for 440i which has dual exhaust holes, but I would like to change tips.

It's the muffler:

I have just take off those tips and now looking for bigger ones.
The inlet is 60mm.

I would like to buy those but there are questions:

- which inner size would be better 60 or 63?
- what is the MAXIMUM size of outside diameter in m performance diffuser?
90 or 100? Can somebody measure that?
