I've got two valves on mine. Dyno pulls with them open and closed showed no difference in power. No need for different maps unless severe restriction, good silencers shouldn't be that at all.
NEARLY 2 WEEKS WAITING: Nissan GT-R is finally mine!
- Thread starter kindai
- Start date
Indeed, the most restrictive part used to be the secondary cats (removed with Y pipe). Everything past that was pretty free flowing.
Right guys, prepare to have your mind blown!
or if we needed more room, loop forwards and move the diverter backwards

Your Paint skills are truly a marvel of the modern world! 
Any reason that option B wouldn't be the default?

How will the center pipe run down the middle with a propshaft in the way?

They're generally offset and then sit under the shaft.

After finding someone who made their own custom valved system for a GTR, they said simply, not worth it, the difference between a race silencer and a straight through is pretty much imperceptible.
So have been looking at some options.
This I love, but unless can find one in the UK, the cost to import it would be extortionate.
Same goes for an Akrapovic system, sounds great but honestly I cant stomach the thought of dropping £3500 on an exhaust.
However found these, and I think the sound is perfect!

I quite like the last option there. What's the cost compared to the akra system?

Doesn't sound like it's worth 1500 quid less. Go for it.
Yea seems like a good option, not sure whether to go resonated Y pipe or not.
However, oh just listen to this... its soo good.
And the other option is Russ fellows:
