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 (see images).

Dimensions: 2" primary, 2.125" secondary, 2.5" exit.

4-2-1 manifold (Rally Spec) - this manifold is an excellent choice for both carburettor and fuel injected engines. It is extremely versatile suiting engine capacities between 2.0L and 2.6L. The key feature to this manifold design is the smooth power curve and wide power band it creates. It is most suited to an RPM range of 3500 - 8500.

Fitment note: the 4-2-1 and 4-1 YB manifolds have been designed to suit both crossmember and chassis mount engines. Due to the wide variety of engine installations in Mk1/Mk2 Escorts, it is recommended that new engine mounts are fabricated once the best engine position has been achieved with the manifold fitted.

Application:
  • Ford Escort Mk1/Mk2 fitted with Cosworth YB 16v aspirated engine

Note: Must use with World Cup crossmember. Does not fit with servo towers. Does not fit Capri.
