Milltek 4-1 Exhaust Manifold - BMW MINI
Milltek Sport has over 20 years of continuous exhaust development and technical expertise implemented into the design of all their products. All Milltek Sport exhausts are produced in high quality type 304 aircraft grade stainless steel. This material is anti-magnetic (other manufacturers stainless steel may not be) and is less susceptible to discolouration. This exceptional quality of stainless steel is used on all pipe work and the total construction of the silencer. Mandrel bending ensures full flow bends for better gas flow and Milltek systems are increased in bore diameter to ensure ultimate performance without the loss of mid range torque. Milltek Sport exhausts have a genuine performance edge with noticeable power gains and sounds that are truly awesome.
The original OEM manifold on the BMW Mini has four short primaries and a restrictive collector followed by two catalytic converters in series providing a very restrictive flow path. The Milltek manifold and sport cat has four longer tuned length primaries followed by a single free-flow (HKS) platinum coated 200-cell German made catalytic converter. 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. Dyno tests have shown improved power gains and mid range torque. The Milltek header is an easy bolt-on installation and it can be installed with your stock exhaust or with a Milltek Sport unit or any other aftermarket unit for that matter. This is one of the first modifications that can be done to your Mini to eliminate the bottle neck from the exhaust system and free up some valuable ponies.
