The ST Sound-Core is a patent pending technology from aFe, compatible with MACH-Force ST and Takeda ST exhaust systems . With this technology, you can easily modify the sound and tone of your exhaust system. By placing the ST Sound-Core in between the two stepped V-band flanges in the exhaust system, you can control the amount of flow that is bypassing the muffler, and change the overall tone of the exhaust with the unique reflection-chamber design.

Nice quality! BF approved.
Size: 9, Color: Olive
I got these for my boyfriend and he loves them. The color green is really nice and the quality is really good. I would recommend doing a waterproof/weather treatment to them if you plan to wear them outside. His got water marks on them already and I didn't treat them. Important note: If you have narrow feet these will work great, but if you have wide feet it might be an issue. They are true to size.
