This Auction for one Maniflow Exhaust header for classic mini engine. as per image.
Maniflow has improved the design and performance of their highly successful LCB in conjunction with top mini racing engineers. Maniflow has now turned their attention to the exhaust system, by creating a reverse cone magaphone setup similar to the race version but in a road configuration, thus creating a better BHP but more importantly a much improved torque and power curve.
This has been done by enlarging and shaping the middle pipe which creates a type of vortex, simulating a pulsing effect similar to the outside two pipes and on the exhaust system, by using a reverse cone megaphone (RCM) to create similar back pressures.
