RC40 system has justifiably earned the reputation of the best exhaust ever made for the Mini. Typically used with an LCB manifold it gives great performance with a mellow sound. 1.75" OD pipe, resonator & silencer ("two-box" system). Side exit. For mounting see RC40FK.

Note, when fitted in conjunction with an LCB header cut the front kink off the RC40-001 pipe(from 5"-8") . When properly installed, the system will fit up nicely into the tunnel and will not drag over bumps
