center and back box question?

[markus_74]

Hello,

Finally I got center box eberspaecher for 323i that is cheaper than 325i, I don't know the size of the pipe and the actual material as it hasn't arrived yet.

Back box I got bosal new old stock.

Anyone tried this mixed system? I will mig or tig welding all this so not worried about the fitting.

And how about bosal quality? I searched at net and forum and got mixed opinions about it some call bad quality but others said it is good and also sound good.

Any opinions?

Thank you
Markus
