Hey gang, what are the most popular mods most new SI owners are doing to their cars? What mods have you guys been doing most and what companies are you getting them from?
The most common mods are the intake, header, and exhaust. As, far as companies go, Aem has their intake out, DC has their header and exhaust out for the new Si, and more companies will be producing mods in the next couple of months.
