Milltek Cat-back - 3 Series - E46 M3 CSL - 2003-2007 - SSXBM462_1
Milltek Sport exhausts are produced in high-quality type-304 aircraft-grade stainless steel. This material is anti-magnetic. This quality of stainless steel is used on all pipework and the total construction of the silencer. Mandrel bending ensures full flow bends for better gas flow and Milltek systems are increased in bore to ensure ultimate performance without the loss of mid-range torque.
