  1. Simpson stainless exhaust manifold: Ford Cortina Mk1/2 Lotus Twin Cam 4-2-1

    Our price:  £625.00 (plus VAT)

    Simpson Race Exhausts specialise in the design and manufacture of exceptional quality inconel and stainless steel exhaust systems and manifolds for all types of motor sport and performance applications.
    This stainless steel exhaust manifold has been handmade to provide maximum performance whilst ensuring it visually looks like a work of art at the same time. The photographs only give an indication of how amazing these manifolds look like in the flesh!
    This manifold is manufactured from 304 grade stainless steel with a wall thickness of 1.2mm. Joints are fully TIG welded which are gas purged. Gas purging provides two benefits. Firstly it prevents oxidisation in the weld which would compromise the strength and corrosive resistance of the joint. Secondly it allows the weld to remain smooth inside the pipe thus increasing exhaust gas flow.
    All bends in the tube are mandrel bent to ensure there is no reduction in diameter throughout the bend.
    All primary pipes are constructed to an equal length to ensure smooth and equal performance from each cylinder.
    All collectors are a fully welded merge type which are designed to maximise gas flow.
    Dimensions: 1.625"" primary, 1.75" secondary, 2.25" exit.
