Supplier of catum equipment Euro2 for 3.6 and 4.2 from BB

Hey, guys.

I am still quite new and hope that I do not ask for something for the second time here. Because on Saturday I will be the owner of a V8 again (4,2) of course I also want to enter into the list well, because it simply pays off.

Now yesterday I sneak through the net and find under http://www.bb-automobiltechnik.de/german.html yet smooth a conversion set for all V8 to Euro 2. Today once called and had a lady on the phone, which was available to me from immediately and approx. 400 euros.
Is this known here in the community, perhaps as an emergency solution, if the 50 orders don't come together? On the page I also found sports exhaust systems for V8.
So, if that was cold coffee of mine, sorry. If not, I look forward to your opinions.
Have a good evening, Marius
Oh so, picture of the exhaust as an appendix...
