a UEL manifold is *usually* cheaper to produce, however, an EL header will make more power per PSI that the turbo is spooling. The UEL is are also famous for their "subaru rumble".
However, for the application that subaru is using it in, I dont think we will see an EL header, based on cost/HP. Yes, the EL will make more power, but EL manifolds usually tend to cost a lot more money.

Huh why? All the Subie boxer engine come with EL header stock. UEL header is after market part (like my Subie).
And correct in the EL header in
Turbo. In NA, they don't make difference. EL header doesn't make more HP than UEL and vis versa. It's just the maker's quality that makes the header HP difference.
