Manifolds and exhaust systems - V8 (Exhaust manifolds): Description and operation (page 2 of 2)

Tail pipe assembly The tail pipe is of welded and fabricated construction. It connects to the intermediate pipe with a flanged joint secured with studs and locknuts and sealed with a metal gasket. The pipe is shaped to locate above the rear axle allowing clearance for axle articulation. The pipe is also curved to clear the left hand side of the fuel tank which has a reflective shield to protect the tank from heat generated from the pipe.

A fabricated silencer is located at the rear of the tail pipe. The silencer is circular in section and is constructed from stainless steel sheet. A baffle tube is located inside the silencer and the space around the baffle tube is packed with a stainless steel fibre. The holes in the baffle tube allow the packing to further reduce combustion noise from the engine. The tail pipe from the silencer is curved downwards at the rear of the vehicle and directs exhaust gases towards the ground. The curved pipe allows the exhaust gases to be dissipated by the airflow under the vehicle and prevents gases being drawn behind the vehicle.

The tail pipe is attached by a bracket, positioned forward of the silencer, and a mounting rubber to the chassis. The mounting rubber allows ease of alignment and vibration absorption.
