Rear Box


Is your rear exhaust box or fitted tailpipe rusty? Is it blowing or does it rattle?

Pentagon Motorist Centre Chatham near Gillingham and Rochester in Medway can repair, replace or renew all sections of an exhaust.

The Exhaust:

An exhaust box that is installed within an exhaust system is designed and engineered as an acoustic soundproofing device to reduce the loudness of the sound pressure created by the engine.

The majority of the sound pressure produced by the engine that emanates out of the vehicle is absorbed through a series of passages and chambers lined with insulation. Exhaust pipes are fitted to guide the exhaust gases away safely, normally towards the ground.

One side effect of using an exhaust is an increase of back pressure which decreases engine efficiency but this is unavoidable.

The Rear Exhaust Box:

The rear exhaust box is attached to the centre silencer or pipe and is designed to reduce noise further. The rear exhaust box normally has a tailpipe attached which directs the exhaust gases downwards towards the ground.

Common Faults:

The most common exhaust failure is the rear exhaust box and being the last section in line, is normally the quickest item to replace. The worst problem when it comes to renewing a rear section of exhaust will be corroded bolts. The quickest and most economical way to get round this problem would be to cut off the exiting bolts and replacing with new.
