Find Replacement Exhaust Rear Box Parts

The exhaust system has the important job of removing the toxic exhaust fumes produced by the engine from the car. It also functions to enhance engine performance, minimise noise produced when driving whilst improving fuel efficiency.

The rear exhaust box is a crucial part of the exhaust system, and its job is to silence the sound produced in the combustion chamber as well as helping to emit the toxic exhaust fumes produced away from the car and the people travelling in the car.

The rear exhaust box is a metal box, fixed to the tail pipe of the exhaust system, containing a setup of tubes and baffles which stops the sound produced in the engine from spreading. As the sound travels through the rear exhaust box it becomes quieter, reducing the loud sound caused by internal combustion. The toxic exhaust fumes travel through the rear exhaust box before passing into the exhaust pipe through which the fumes travel to reach the tail pipe where they finally leave the vehicle. 

The rear exhaust box will eventually need replacing simply due to wear and tear and old age.  Often the main issue with any exhaust system is problems caused by rust.  Internal components are subject to moisture created by the process of combustion and rainwater can cause corrosion to the exhaust system. The rear exhaust box is no exception to this. Rust can cause cracks and holes in the rear exhaust box and eventually it will stop functioning properly. When replacing your rear exhaust box, it is important that you purchase the right rear exhaust box for the make and model of your car.
