2015 - 2021 スバル WRX/STI AFD F1 バルブ付きキャットバックエキゾースト

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.

Quite simple to install and love the sound

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

Cost makes it hard to justify by having the ability to make you car as quiet as stock around the wife who hates cars or the sleeping baby is priceless, and open pipes pop twice as much as my Borla on down shifts. Sound clips on IG lateralgs
