Want a little stance and sizzle for your G30 540i? Look no further as Dinan is pleased to release our exhaust system and spring kit for the model. The ultimate sleeper, the 540i is an often underappreciated platform that can be converted quite easily into a wolf in sheeps clothing. A bit of a drop (7/8" at all corners) that improves handling while retaining its naturally comfortable ride and a deeper, throatier exhaust note are the start to something special. .
