Thanks a lot Bubu!
3. The mounts are different. Either you order the new ones or you have to bend your old ones properly
These things?

5. Maybe a tiny bit, but dont expect much from it. This mod is just for optical purposes
I don't want extra noise. So it's a good thing the sound stays the same.
Sorry this is in English, I don't speak or could not write in German and I can't find answers in Dutch fora. 
I want to swap my F31 320d (N47) rear silencer to an OEM 340i silencer.
I've got some questions about it.
1. The 340i rear silencer is bigger and heavier than the 320d silencer. Gives the 340 silencer more backpressure? So, after a while it could damage the turbo and/or DPF of the 320d? Yes or no?
2. I need an adapter piece to go from the 320d tube (55 mm) to the 340 tube (80 mm). I guess an adapter with outer dimensions of 58 mm (slide over) to 76 mm (slide in) is the best option?
3. What extra parts I need to order? I guess another bracket, support to hang the 340 silencer on it? Other parts I need to order...?
4. On the 340 silencer there's no vibration absorber mounted. Is it okay to mount it on the 320d without the vibration absorber?
5. Is the 340 silencer louder, or is it the same as the 320d silence?
Thanks!
Thanks!
Is 76-58 mm maybe better? Than the adapter can slide over the 55 mm 320d tube?

i will take one, once i have time.
yes one time but you can also use a clamp
Where did you buy the adapter to go from 55 mm (320d tube diamter) to 80 mm (335i tube diameter)?

Thanks for the quick answer. You got a picture of the underside? You have to weld some things?
Thx.
Sorry it's in Englisch. Don't speak German.
How is the sound with the 335 exhaust? Still the same as the original 20d exhaust? Do you've got a picture of the underside? Easy to install? All info welcome. I'm very interested to do the same on my F31 320d.
Thx. 
Danke. Noch bilder.
