Honda Accord/Civic/Prelude 1973-1983 Repair Guide

Special Tools


A number of special exhaust system tools can be rented from auto supply houses or local stores that rent special equipment. A common one is a tail pipe expander, designed to enable you to join pipes of identical diameter.

It may also be quite helpful to use solvents designed to loosen rusted bolts or flanges. Soaking rusted parts the night before you do the job can speed the work of freeing rusted parts considerably. Remember that these solvents are often flammable. Apply only to parts after they are cool!


Once or twice a year, check the muffler(s) and pipes for signs of corrosion and damage. Check the hangers for wear, cracks or hardening. Check the heat shields for corrosion or damage. Replace components as necessary.

All vehicles are equipped with a catalytic converter, which is attached to the front exhaust pipe. The exhaust system is bolted together. Replacement parts are usually the same as the original system, with the exception of some mufflers.

Use only the proper size sockets or wrenches when unbolting system components. Do not tighten completely until all components are attached, aligned, and suspended. Check the system for leaks after the installation is completed.
