Exhaust manifold, part of the Four Ashes 'Adspeed' range of improved, fast road or race products,

This is an improved six branch (over std style cast iron manifolds & other suppliers / manufacturers fabricated to STD manifold parts) with 16" long primary pipes, stainless steel manifold to head flange, very good collectors hidden from sight, free-er flowing than any comparable manifold & quieter too - even than std manifolds.

It has the correct orientation for manifolds as AML intended, ie front manifold feeds right hand system, rear manifold feeds left hand system, there is plenty of clearance around steering box & drop arm nut so that the middle tube doesn't need hammering in, with other features to improve the system, very easy fit,  

As its made to order it comes with correct dia for primary pipes:

2.6ltr 1.625" 42mm

2.922ltr 1.750" 44mm fast road

2.922ltr 1.820" 46mm race.

Not sure this is FIA legal, depends on / up to your local FIA scrutineers.
