It's not. Evolution got 36 rwhp from a mid-pipe, drop in K&N, mufflers and an unfinished tune (I'm assuming they have yet to play with VCT tables), and those factory headers are garbage. Mike Harrison has said those headers were worth 5 flywheel HP over the 3V logs, and it's not uncommon for a proper set of long tubes to see 20 HP.
Drop in a JLT RAI, 110mm MAF housing, LT's, 3" exhaust, aluminum driveshaft, and a full on tune and these things will be laying down 430-450 rwhp. The car above with minimal mods already made 405 rwhp.
I think there are gains to be had from the intake manifold as well, note the Boss302Rs already have a different manifold. The factory 80mm TB is going to be marginal once everything else is opened up as well. The Coyote engineers already admitted the 80mm TB cost them 3 HP ([censored] near offsetting the "header" gains) over the Shelby TB, so once inlet, exhaust and the tune are improved that is likely going to turn into 10+ HP.
Glad to hear my source was inaccurate. Part of the draw of this segment is mod-ability.
