Correct. Also keeping it quiet around town and if I'm down on power to 300rwhp out of boost with factory x5 mufflers it will still be plenty fast and once the car starts to build boost the cutouts open thus me having no restriction at all. I still haven't decided that I'm doing this exact exhaust setup but it's definitely one of my top choices.
