JDM Subaru Forester SG9 STi with HKS Silent Hi-Power Exhaust & Straight Centre Pipe

スバル フォレスター SG9 STi バージョン
HKS サイレントハイパワー
純正では、フロントパイプ部とセンターパイプ部の2箇所に触媒が有るのに対し、当商品では、フロントパイプ部のみ触媒一体型となり、センターパイプ部は膨張管のみとなり大幅な排気抵抗低減を実現。

The centre section was changed from the previous specification, in the genuine product, there are catalysts in two places, the front pipe part and the center pipe part, but in this appilcation, only the front pipe part (downpipe) is integrated with the catalyst, and the center pipe part is now only the expansion pipe, realising a significant reduction in exhaust resistance.
With the straight pipe centre the sound is louder and more aggressive as a result but it is still perfectly liveable at motorway speeds.
Sorry about the wind noise, I forgot the windblocker. I will update this video when I have more time.
