The 2008-2013 BMW M3, with its high revving 4.0L V8, can now rev up much faster with a new 304 S/S header system by American Racing Headers. With real gains of 40 RWHP and 35 RWTQ (before tuning) on a bone stock M3, American Racing s new header system will literally transform your M3 and take performance to a whole new level. There is simply nothing currently offered as a package that provides the incredible HP, Torque and Sound. The full system provides a deep, throaty tone without high pitch rasp. Best of all, kit is 100% USA made and built to last indefinitely.
