Be aware that cutting where you want to cut now, will mean that the exhaust is bolted "hard" onto the engine with no flexible bit in between to isolate the engine motions and vibrations from those of the exhaust system. This will usually give you cracked exhaust piping within a very short time frame.
First of all thanks for your advices.....
I have already one 60mm flexible pipe in order to prevent problems described by you.....

Make sure you make the radius in those 60mm big enough, or the bend will still rob a lot of flow. If you really want to make sure you're okay, don't merge the two banks and use two 50mm pipes.
Sounds OK, but i guess both banks must be merged because the lambda must read from all 6 cylinders......anyway if not a problem to use 60mm "merge" pipe, to avoid restrictions i may use bigger as well, right......

What we had here to drive on, can hardly be called "a track"......We drive on Serres circuit as well and have no problem with them......and as you may hear from this year's event my car was noisy.....

Don't get me wrong, and no offense to you, but......
- i can't invest in a project that was never done before with Alfa 156, have no idea if the whole conception work fine or not.....
- if this works OK, i dont plan to use only 2.5V6 - have 2.0TS engine and Fiat Coupe 20VT - all engines interchangeable on 156's - that's why i rather prefer to invest in suspension and slick tires(very hard to find proper ones here in Bulgaria) - i don't plan to use this car in Monza, Spa, SIlverstone or any other really fast track.....
- maybe silly excuse for someone, but some people here in my country must work at least half year, just to be able to pay for the price for the custom exhaust work that you describe above.....:).....i do this just for "very serious fun and hobby"......
As i said - no offense to you - we don't know about each other's situation and point of view.....i just ask for some advices......
