This Milltek BMW 428i catback exhaust is crafted from non-magnetic, type 304 stainless steel throughout the entire system. The result is a high-quality finish that resists discolouration and is built to last. Mandrel bending maintains a constant radius through every bend to maximise gas flow, helping to enhance response without sacrificing mid-range torque.
