Mini R50 R52 R53 Gen 1 Janspeed Manifold
The Janspeed high performance exhaust manifold for the bmw min cooper s is easily the best performance manifold on the market. It uses a superior size pipe boar over the stock manifold which is the most restrictive element on the cooper s engine. Due to a much larger pipe boar gas flow if further increased resulting in far greater power gains for BHP and torque. These gains have been seen time and time again on the dyno. One of the main advantages of the janspeed high performance manifold is the size of the exhaust ports. They are much bigger than stock and allow for even modified heads running larger exhaust ports.
Janspeed Bolt in De- Cat
The Janspeed bolt in de-cat has been designed to be easily removed for occasions such as track days or any off road driving, further increasing gas flow and performance. For on road use the High flow sports cat can be used as an alternative to the de cat allowing you to swap between the two dependent on what your using your mini for.
Janspeed Sports Cat
Mini standard OEM cat uses 400CPI unlike the high flow sports cat which uses 200CPI. The sports cat is only suitable for vehicles running around 160BHP. The janspeed sports cat combined with the manifold will help to increase gas flow and further increase a noticeable power gain for any cooper s.
