Absolutely amazing exhaust, loud, low rumble, and beautifully designed. REMEMBER TO BUY A DONUT GASKET AND THE OEM TO 3” ADAPTER TO INSTALL THIS. It comes with everything but the adapter

Great no drone exhaust

This exhaust is perfect if u want something thats gonna have some nice sound but also be able to have a conversation riding down the highway at 70. There is no drone at speeds. The sound is awesome and has a nice 3rd gear crackle to it. A very easy install. With a lift i was finished with it in 45mins. Overall 100 percent recommend it. My son dropped the camera in the video but thats how it sounds on my wifes 2020 wrx
