Like <2 HP difference. Both saw gains across the torque curve over stock as expected. But the 2hp was to the uel down low and 2+/- up top was the el. So maybe a tune would accentuate characteristics? My experience with air cooled vw says it doesnt matter. But there's about 80 years of engineering difference there haha

on thing i'm curious about is to see how all the other headers compare. borla's design looks nothing like the nameless or JDL designs so i wonder if the other headers will net more gains vs the borla EL and UEL. thats really what i'm waiting for.
