Exhaust sounds like its blowing.

But it isn't!

There's a slight burble /spitting noise comiing from my back box. Expected to have to replace the back box. Noticed today the noise is actually coming from the tip,of the exhaust.

Have been under the car while someone put their hand over the exhaust, brut I can't find any blows at all (it sounded quieter when hand over the end!) and there's no corrosion at all on the back box.

Any ideas? Mot on Friday.

Maybe the back box baffles are falling to bits. I don't think that is an MOT failure. Wait and find out...
