mine is just installed and open. still def quieter than the straight pipes i had...but if you want quiet and loud...leave your mufflers on and alone, put in an electric cut out. i have one on my turbo downpipe, i am also cammed. it creates some sound lol. honestly the car is damn loud with it closed too (no cats etc.)
