The OEM manifold on the MINI has four short primaries and a restrictive collector followed by two catalytic converters in series, giving a flow area of approx 60%. The Miltek manifold and Sport Cat has four longer tuned-length primaries followed by a single free-flow Catalytic converter. This results in a flow area of approx 85% while remaining clean enough to meet emissions requirements.

Dyno tests show a 12 bhp improvement on a Cooper S and increased mid-range torque. Incorporates a triple-wall flexible section to a much higher specification than the twin-wall OE header to allow for the greater loads imposed by a tuned engine. Accelerated gas-flow draws heat away more efficiently to reduce under-bonnet temperatures - particularly important for a tuned engine. The two original oxygen sensors are retained in their correct position for the proper operation of the OBD2 (on board diagnostics) system. A perfect match for the Milltek Cat back exhaust or one of the other fine aftermarket exhausts.
