Subaru ff-1/1300/1400/1600/1800/Brat 1970-1984 Repair Guide

General Description


The exhaust system is suspended by hangers and clamps attached to the frame member. Annoying rattles and noise vibrations in the exhaust system are usually caused by misalignment of parts. When aligning the system, leave all bolts and nuts loose until all parts are properly aligned, then tighten from front to rear. Make sure that you are wearing some form of eye protection when removing or installing the exhaust system, to prevent eye injury. Never work on the exhaust system of a vehicle that has been recently used. Exhaust systems reach extremely high temperatures and can cause severe burns. Always allow the car to cool down before starting any repairs to the exhaust.

The Catalytic Converter is an emission control device added to a gasoline engines exhaust system to reduce hydrocarbon and carbon monoxide pollutants in the exhaust gas stream. The catalyst in the converter is not serviceable.

Periodic maintenance of the exhaust system is not required. However, if the vehicle is raised for other service, it is advisable to check the general condition of the catalytic converter, exhaust pipes and muffler.
