Exactly, I just don't own the sled yet, still looking for something local and well maintained.

So I don't know exactly how big the inlet is on the intake. I'm pretty sure the I/C piping goes into the intake then the intake has two throttle plates on both of the runners.

Once I figure out the size of the intake inlet I will just use that that for I/C pipe diameter size.
