New LS3 instake manifold

Very interesting. In the write up they say it will be LS and LT series heads. Cant see it saying LS1, but it does look nice. I will check out their website later.
 
On top of the cost of the manifold you will need a 2nd Throttle body and I guess 2 MAF's.
Not a cheap upgrade for the gains you would see.
 
2 MAF's would be a bit of an issue, although could make something to join the two signals in, a total value for the single input on the ECU. It looks different, but not a lot of gains over what I already have. Probably good for a twin turbo setup. I would want wide band exhaust sensors on both sides though to make sure one bank isn't running leaner than the other.
