Ok here are the first impressions after driving it about 100 KM.
The MB mech that did they installation said it was not an easy job. They had to cut and weld and make adjustments to fix the entire thing. Both headers and cats have been installed and the resonater has not been removed (not mandatory according to MBK).
First the bad news > as you can tell from the pic the metal cats are larger than the original cats and therefore hang lower. There is nothing that can resolve this due to lack of space. It means I have to be very carefull when going over traffic bumps. It is annoying but hey most of the time we drive on normal roads and all is OK. I will take a measurement tommorow to see how much room is left underneath the cat.
The rest is all good news.
The sound is just a little deeper eventhough the resonator is still in place. At WOT there is about 20% increase in sound. It sounds very different from to stock at WOT. It is much more like a sports car like with that increadible metal flavor to it.
In terms of power their is definately a gain, especially in the high revs. My butt dyno tells me at least 20 HP but lets wait for the real numbers. Howver the increase in power is nothing like what I experienced after installing the ODPS kit. It did not give me that whooh feeling. Maybe the ECU needs some more adjusting before all the new power gets released. So I am gonna drive it around for another week or so before going for a new Dyno.
Stock weels are really taken a beating now and are actually loosing too much grip during acceleration from a start. ESP gets a lot of work these days haha.
Next > ECU tuning
@Vadim :
I noticed that the cars temp goes up to 95 Celcius at stop and go heavy traffic. When I drive normally (not traffic jam) temp are +- 85 C. Is this normal ? Ps > enviroment temp the last couple of days was about 16 C. Thx, Bart.

Bart, I am glad you got the headers on. The cats do hang too low. I am surprised MKB could not do anything about it. On a lowered car it will be a problem.
We have done some more testing with an H-pipe that did not have any cats and saw another 14HP (330HP). However, this setup is not legal in US. We just wanted to see how much restriction was due to factory catalytic converters. My guess your gains with headers will be around this number.
As far as your coolant temperature, it is a bit high. Did it start after the header install?

It's a good move !
Coolant temp arised after ODPS+I/C as I posted before
ODPS users here all downset the fan start temp -5 C & keep coolant temp < 91 C always.(before the reset I read 101 C)

Anyway, my next step is up-grade the exhaust, and I am really interested of every development, specially yours....I really like the EVO headers.
Thanks! Bart
Bye
(PD) Next week I will dyno my new set-up, and Vadim I will send you my DynoJet files.

@Vadim
I will visit MKB in Stuttgart on my next trip to Munich. They will have a look at it and hopefully lift it a bit, even if its a few cm.
I never had a good look at the temp before installing header or even odps so I dont really have a reference.
@Shine.
Can you tell me how the -5 degree Celcius fan is done ? Is this something that can be set in the ECU or is it a mechanical change ?

Shine: Stock pipes at catalytic converter inlet are 2.25'', we fabricated 2.5'' down pipes without any cats. We welded four oxygen sensor bungs in the stock location, so DME was happy.
Bart: I am not sure why your car runs hotter. Of all of the installes we have done in US, they all ran the same. Shine mentioned that his dealer set his cooling "fan on" temperature lower and now his runs OK. I am thinking perhaps there is a difference in European and Asian cars when it comes to cooling strategy.
Good Luck at MKB.

;nevertheless, I do not like the idea of remove the stock cats because you will loss back pressure. My point is to optimize the extra flow of exhaust gases that the EVOheaders are throwing inside of the stock 2.25" stock pipes. Thus, I believe if you leave the stock cats and just increase the down pipes to 2.5", as you mentioned, flow will increase at this region of the exhaust and the back pressure as well too....

Vadim , you maybe right since we've never compared the difference before.
Bart :
Here comes the procedure :
ME-SFI -> Control unit adaptations -> setting of correction programming -> electric suction fan for engine or air conditioning
Press F5 to cut the fan start temp from default.
