The aFe MACH Force-ST ST Sound-Core 1.25" insert is a patented exhaust tuning component that fits MACH-Force ST and Takeda ST systems to alter tone and sound level. Placed between stepped V-band flanges, the reflection-chamber design changes exhaust character and controls flow bypassing the muffler. Made from durable 304 stainless steel, it bolts in for easy installation and sound tuning without valves.
