Exhaust Noise

[Sanandreas21]

I have got a twin exhaust on my car and it makes a loud rattling noise when the car starts up and when you start to rev the engine.

I have been told that there could be a hole in the exhaust but does anybody have any other ideas what the noise might be before i get under the car when it finally dries up and there is some light.

Thanks

it could be the exhaust touching the rear beam or maybe a loose clamp....you will have to get under it and have a look

sounds like its rattling on the rear axel beam
if you have an aftermarket backbox chances are its just knocking agaisnt it
you probably need to raise your backbox so the exhast isnt hanging down as low

Thanks for the replies.

I will have a look tomorrow when there is daylight

It'll be it knocking on the rear axel crossmember, mine was doing that i had do move the middle box further forward off the cat.

Just a quick update for you.

The insides of the backbox are all loose and rusted along with the pipe going into the exhaust.

Looks like i need a new 1
