It is amazing makes my turbo sound so good and loud after letting off the gas would highly recommend
This blow off valve sounds better than any other I've ever owned. Gives off a loud chirp, some of my friends say that they hear the bov before they hear my exhaust when I pull up. Easy install, everything needed was included. Great purchase.
Definitely worth the money! Fits perfect and sounds amazing Shipping was fast, as always.
Easy to install and delivered super fast. Sounds amazing! Great build quality and looks great.
Boy! This is one sick a** bov ...it's so loud as soon as you hit boost....have no issues or no regret...
