Manifold and exhaust system - Td4 (Description): Description and operation (page 2 of 2)

The catalytic converter is located between the forward flange and the silencer and is integral with the intermediate pipe. EMISSION CONTROL - Td4, DESCRIPTION AND OPERATION, Description.

CAUTION: Ensure the exhaust system is free from leaks. Exhaust gas leaks upstream of the catalytic converter could cause internal damage to the catalytic converter.

An oval section silencer is located behind the catalytic converter and is braced to the pipe at either end to resist bending. The pipe has a series of bends to allow clearance for the suspension and terminates in an open end which mates with the tailpipe assembly. The intermediate pipe is supported between the catalytic converter and the silencer by a welded support bracket and a mounting rubber.

Tailpipe Assembly The tailpipe assembly is of fabricated and welded construction and comprises a large capacity silencer, a connecting pipe and two tail pipes. The curved connecting pipe is welded to the left hand end of the silencer and mates with the intermediate pipe. The connecting pipe is a sliding fit on the intermediate pipe and is secured with a clamp.

The two tail pipes are welded to the right hand end of the silencer and direct exhaust emissions downwards from the right hand end of the rear bumper.
