BMW M2 G87 Dinan Freeflow Midpipe Exhaust OPF / GPF Delete

Made from high quality T304 stainless steel with TIG welding, this Dinan midpipe exhaust fits without modifications between the secondary catalysts and the rear silencer of the BMW M2 G87 in order to remove the resonator and the OEM OPF/GPF. Designed to bring an aggressive tone to the S58 engine, this 3" / 76mm centre pipe will also provide a power gain of around 27hp but will require a revision of the electronic management following the removal of the particle filters
