    Fantastic quality/ Moderate Loudness/ Zero Drone 1 year ago

    I've been running with this exhaust for almost a year now. If i am honest, there are moments where I wish it were ever so slightly louder, but i know that i will most likely regret a decision to switch it out for a Tomei (even though they sound amazing). Its a perfect gentlemen's exhaust. Noticeable enough of a difference compared to stock.

    Great quality, price and sound. No adapter needed when fitting to stock down pipe. Very reasonable sound levels with a nice rumble and no drone. Gets slightly louder as it breaks in so don’t be too worried when you start it up and it sounds mostly like stock!

    I’ve installed this on my 2021 WRX and at first it was so quiet more so than stock and now that having it on for about a month is sounds so good just the right deep tone compared to how most single exits sound. I definitely feel a small power difference. Hands down 10/10!
