Maniflow's tubular interpretation of the original Mini Cooper and S exhaust manifold manufactured out of the same tubing as the standard bore LCB. This free flow manifold works very well at lower speed pick up. (The LCB is noisier but better at the top end of the rev range on very mild tune cars.) Requires adapter L71 for fitting to Maniflow 1.75" exhaust systems, as this manifold is designed to fit the RC40-001 downpipe for the RC40 system. This manifold requires a longer downpipe as it is shorter than the type used on LCB fitment. 
Works well on mildly tuned 998s and 1275s.

One of the easiest bolt-on modifications you can make to your Classic Mini Cooper is a performance exhaust manifold (also often called a 'header') A good exhaust manifold make it a lot easier for your engine to push exhaust gases out of the cylinders. All internal combustion engines produce all their power during the power stroke. During this stroke, the gasoline in the cylinder burns and expands to generate power. As the exhaust gases are pushed out of the cylinder, they end up in the exhaust manifold. The ease at which these gases vacate the cylinder head is a big contributor to performance. The exhaust header helps eliminate the manifold’s backpressure. The length and diameter of the exhaust manifold pipes are all part of the science of performance.
