What is a SSC, and why did you add it to your RS?

The Mountune Sound Suppression Chamber (SSC) replaces the OE resonator found on the stock Honeywell turbocharger compressor housing. When an aftermarket high flow intake (filter or upgraded housing) is added to the Focus RS the increased flow causes a whistle effect across the factory OE resonator. To cancel out this annoying whistle Mountune has created this SSC. A few minutes cussing the factory Snap Ring and the job is done. REMOVAL OF THE PASSENGER WHEEL/TIRE IS NOT REQUIRED!
