The MINI Cooper O.E.M. header incorporates four short, varying lengths, 1.25-inch primary pipes attached to a tiny, restrictive collector and flexible pipe section. This is followed by two 400-cell catalytic converters in tandem, offering an approximate 45% flow area, connected by 2.25-inch pipe work. This arrangement, in terms of performance, is inefficient. Unlocking power from the MINI Cooper involves carefully tuning the header to work with the MINI's engine and the Eaton supercharger of the "S". The Madness MINI Cooper V2 Header incorporates four maximum, equal length, 1.50-inch primary pipes, mated to a collector of increased length, followed by a high performance flexible joint. Attached is a single, 200-cell, high flow Metallic Sport Catalytic Converter, offering a flow area of approximately 85%, coupled to 2.50-inch pipe work. This arrangement is the performance ideal. The two original O2 sensor probes are retained in their correct positions for the proper operation of the OBD II (On Board Diagnostics II) system

This is an amazing header. Got lots o' torque from it. I really liked seeing the fat welds and the flange is really thick to prevent cracking. It is also the only header I have seen with an interchangeable test pipe or high flow cat.
