Milltek’s M135i (F20) performance exhaust system
Milltek has released details of its new performance exhaust system for the new BMW M135i. The latest F20 chassis car features BMW’s twin scroll turbo engine, which Milltek says suits its extraction technology and craftsmanship. Initially launched as a cat-back only set-up, Milltek will provide the additional option of a turbo-back system, complete with large bore downpipe and high-flow cat configurations.
