So far happy with the Borla.

Tandrew,
Similar observations to what I have with the Corsa exhaust on my H3. Slight amount of drone 50-60mph but at normal California freeway speeds (70-85+) almost quiet as stock. I only notice slightly more power when pulling long grades in 2nd or 3rd (auto tranny).
