The primaries are no where near 2.5 inches. The collector is.

Was it really necessary to make 2 threads for this?

Indeed maybe 1 5/8's at the most and the 4-1 collector would be a maximun of 2.5 because over that with a N/A set up would seriously decrease performance..I've noticed the common primary is around 1 5/8 for all kinds of USDM and JDM vehicles..weird lol.
