Built to perform, built to last
Milltek’s aerospace grade type 304 stainless steel construction offers outstanding durability and resistance to discolouration. Every section of the pipework, silencers and associated hardware is engineered to exacting standards. Precision mandrel bending maintains internal diameter through every curve to maximise gas flow, support throttle response and keep the 128ti feeling eager across the rev range.
Tuned sound without compromise
Each Milltek system undergoes a rigorous acoustic development process. The result on the BMW 128ti is a genuine performance tone that is deeper and cleaner than stock, with zero intrusive drone on the motorway and a refined in-cabin character for daily driving. The GT-115 Cerakote Black trims complete the look with a purposeful factory-plus aesthetic.
