What can I expect with these mods?
Today I booked a time to have a company make a handmade double stainless steel full flow exhaust with 2 high flow sport catalyst instead of the 4 original once. And after that I'm going to take my car to a tuning company to let them tune the electronics in the engine for 99 octane Shell V-Power fuel.
I wonder what I might expect after that? Close to 400 HP ought to be pretty reasonable right??

I would say small power is to be gained from eliminated 1 set of cats... maybe 5-10 whp. also a bit from high octane software and fuel.... but you're not going to get 400
Are you doing custom headers as well?

Could you please tell me why you think it won't add any power? I've heard of a few with E55 over here that has done the same mods and tuned the software and they say that there was a big improvment in power.
Just to clarify. With the new exhaust there will be only 2 2 high flow sport catalyst in total (not 4). And the last silencer will be replaced with a high flow silencer.
Ok if it won't add any power at least I get a more masculine engine sound

An update.
I tuned/changed the software here in Sweden today at a really good company which have been tuning (AMG's for an example) for over 10 years in Germany. And though I still have the stock exhaust system (Will change it in 2 weeks) I have to say that there is actually quite a big difference in both torque and power
And with the new exhaust system I think this car will be really fast I'm going to take it to a dyno machine to let me know how many HP I have.
They also opened up the V-max limit, and I had to try it on the way home (Empty highway of course) and when I hit a little bit over 270 Km/h I had to break due to the road started turning, but the car was actually still pulling. So a 280 Km/t on the meter or more shouldn't be a problem when the exhaust is mounted I guess

hi there, you talk about a hi flow exhaust..... if you take your standard 1 off and look through the rear box it is TOTALLY STRAIGHT THROUGH... so a it is in essence a hi-flow..... if you cange the back box that will be noise only!!
the main advantage i think would be to get some headers made!!
