I have a 3 inch upper intercooler pipe. I have seen people say the TB uses a 2.75 inch and also 2.5 inch. I need help finding a white silicon coupler to go from the Upper intercooler pipe to the TB or at least info on the OD of the TB.

 

I was able to measur and verify its 2 3/4. Anyone know where to find a coupler or a place that would make one
