This is how I did mine- Because I used a T-4 turbo (modded B&B headers) on stock style B&B's, it boost creeped like a mo-fo. I also
upgraded to a Tial V-44 and still got some boost creep.
For your setup I would throw twin 38's on either side with a nice 35r. No- you dont need that long a$$ wastegate tube- that is so you could run the wastegate in the stock position.
I am having new headers made from scratch to help eliminate the boost creep problem. (that is going to be twin valute as well)
Oh and as for the second picture- my buddy has a 700 horse Eagle Talon that has a twin valute with a single gate and it works well
