Gearbox

If you’ve ever crunched your gears when driving, you’ll know how the sensation makes you wince. The sound of all those cogs and metal parts grinding together can set your teeth on edge. All those fast-moving parts are housed in what the British call the gearbox, and the Americans call the transmission.

Of course, keeping everything running smoothly in your engine means using lubricant, so make sure you know the best lubricants to use.

Exhaust Pipe

All the emissions from your car engine need to be expelled somehow, so pumping them out the back of the car is the most sensible solution. Not only is this safer, but it also cuts down on engine noise. If you get a hole in your exhaust pipe (known to the Americans as a tailpipe), and you’ll sound like a Formula 1 racer. You’ll use more fuel too, so keep your tailpipe in good order and fix any holes right away.

Silencer

The silencer does what it says on the tin—it keeps your car engine from sounding too loud. The American term muffler is similar. With a faulty muffler, your car will rouse the neighbors every time you drive away, and the police will take a dim view of you.
