The Milltek difference
Every Milltek system is engineered for real world performance and long term reliability. The T304 stainless steel construction is less susceptible to discolouration and is designed to last. Mandrel bending maintains a constant radius through each bend to maximise exhaust gas flow and response. The result is a performance exhaust that elevates your M135i driving experience with a refined, characterful tone and high quality finish.
