An Irritating Noise!!!

[MrTackalakalaka]

Hello Everyone

I have had quite an annoying noise coming from underneath my car for sometime now! It used to come and go but now its pretty much all the time. Its kinda like a buzzing noise.
I dont think its a hole in the exhaust.

I believe its coming from the cat........the noise happens if i accelerate but mainly when i let off the accelerator and the revs are dropping (whilst moving or parked up). It occasionally happens at idle as well.

Any ideas on what it could be?

Cheers
Scott

Sounds like the exhaust is touching something. Get underneath and have a look about!

Ok will do! Not very mechanically minded but will have a look about.
