An efficient exhaust configuration, all the way from the cylinder head to the back end of the car is essential to achieve the full power potential of any engine. On a standard (stock) specification engine or even a 'radical' improved one, a good exhaust setup is worth loads of extra bhp's.
 
A Four Branch Manifold (for 4 cylinder engines) similar to the one shown in the picture overcomes the problem with most standard manifolds where exhaust gas flow can be affected by other cylinders. Here the flow path from each exhaust port is independent until well after the 'close timing' of the exhaust valve.
Replacement "exhaust systems"  which means all the pipework and boxes starting from the end of the manifold (or downpipe or catalyst) backwards, are available from different manufacturers in a choice of materials, tailpipe designs, flow efficiency and noise characteristics.
Only Full Systems are displayed on this page, for "Backbox Only" options please phone or e-mail with car make & model requirements
Catalyst Converters - Required by law on all UK cars first registered K and later. Contrary to popular belief, cats are only about a 2% restriction to exhaust flow.
Stainless Steel, this is an 'exotic' material being used in a rough environment, it needs to be well engineered to live up to it's promise of long life.
Life-time Warranty means - while the car remains in the ownership of the system purchaser. The Magnex warranty requires an annual system inspection.
