I never did reach out about my floppy nipple. Thanks for the reminder.had mine on for about a week. I think the sound is nice. With stock airbox and the typical DIY mods you could sorta hear the turbo with windows down. Now you can definitely hear it (especially windows down) but its not obnoxious or anything. Like others said, if you want max noise, get an all metal one. My APR intake is used with MST TIP and MST hose.
Great product for the price, seems silly to have another intake on an already super saturated market, but obviously there was a desire for a high quality / affordable one.
Oh and my nipple was plenty stiff too.
