2015 - 2021 Subaru WRX/STI AFD F1 Valved Catback Exhaust
I've had this exhaust for about 3 months already. It's paired with an Invidia catted j-pipe and stage 2+ with extra/ tuned. The quality and sound it makes is unique. I would buy it all over again. When the valve is closed you dont hear any hum through out the inside of the car, quieter than stock. Valve open turns your car into a scamming banchi. The installment took about 5 hours if you are using car rams instead of a car lift. You can do in your garage. It's well worth the time it takes to be built and money. If anyone wants i can post a video of the sound if you want. Thank you Arrow for making a quality product.
Very good and high quality sounding exhaust. Everything is well made and you get what you pay for. Only complaint is that the remote could use some labeling so you know when it’s open and when it’s not. Other than that, it’s an excellent exhaust
