  1. Incredibly Low / Aggressive Tone With Great Looks

    By Josh W January 8, 2017

    I put this cbe on my '17 Forester XT as for my taste, I wanted the quietest exhaust I could find as this is my daily driver, but I also wanted to hear the power when I give the subie some gas. The system lined up perfectly, went on very easily and has a nice look that closely resembles the stock exhaust. The low tones out of this system are incredible. In my opinion, the note is so low that it can feel deafening in very low RPM's. So in that regard, the exhaust feels louder than i was expecting. But the actual volume of the system is quiet, but the sound is awesome. You can hear the turbo out the back of the car now, which is pretty sweet. If you want a quieter system with more of a clean/stock look, I would go for it vs the N1, which is a louder and more aggressive looking system in terms of looks.
