Great exhaust Review by Chris
I have this exhaust fitted to my 2008 Hatch STI. Gives a really nice but subtle noise on idle due to it being the resonated version but opens up with the throttle. Quality and fitment is great and easy to adjust tailpipes based on how it sits on the car to get the perfect look. (Posted on 01/02/2017)
