Product Description
Our Stage III package for the 2008-2013 E90/E92 M3 is a 3-part upgrade: intake, cat-back exhaust, and software. We don't touch the center section and catalytic converters so this kit is fully emissions legal in 49 states. While a lot of power can be gained by removing the catalytic converters, this is not always desired or possible for some customers. Our Stage III gets the most from bolt-on modifications without hassle and side effects of cat-delete.Macht Schnell E9X M3 Intake
