Airtec Motorsport Resonator Delete Pipe for MINI Cooper S + JCW Models. AIRTEC part no: ATMSMINI15. MINI F56 – (04/2013 to 12/2019). MINI Cabriolet F57 – (11/2014 to 12/2019). The manufacturer fits these resonators to reduce noise and quieten the tone, but by replacing the pipe for one without the baffled internals, flow is improved, as well as noise.
