Update: To make everything as discussed, it would cost me about $100 to make each intake.
Not worth it.
So I am downgrading the MAS adapter to the 3" plastic one, instead of the previously planned 4.5" aluminum adapter. Also, the stock 7G throttle body is 52mm, which is barely over 2"; and even if you upgrade to the 60mm throttle body, that's only 2.36". So instead of going with 3" pipes, I'm downgrading it to 2.5" pipes.
This will offset the cost to make the kits. Let me know if this pisses anyone off. It should still allow for optimal airflow, and there's a 0.5" increase over the stock TB, so there's still a significant amount of air on demand for the TB.
