Front Section: Notes

The front section comprises two separate pipes each incorporating a catalytic converter. Each catalytic converter has a welded pipe with a flange, which is flared into a cone which mates with the exhaust manifold. Each flange has two holes which locate on studs in the exhaust manifold and are secured with nuts. Each catalytic converter is fitted with a mid-brick catalyst HO2S.

A pipe from each catalytic converter locates into the front silencer inlet pipes of the center section. Each pipe between the catalytic converters and the front silencer is fitted with a post catalyst HO2S. The left pipe is fitted with a mass damper which absorbs resonance from the system.
