    I say high flow, it helps reduce rasp.

    I guess it would depend on whether the inspector still has to physically see one or not... I know here they still look to see if the car still has one when doing a safety inspection.

    high flow unless you enjoy the sound of the riciest thing you have ever hear. I'm talking rasp at 3k while driving

    Reading down on that post that car is modded and heavily tuned. That's not an average Stock v6.
