    It can be anything Liam can't just say what it is .. you have already looked at the exhaust I presume under the hoist? there will be something lose,rusted, busted or touching without looking at its hard.

    I can't sorry. Just a faint tingling noise coming from below sounds tingly springy but then it goes away. Only happens blipping the throttle. Is the manifold a big fix?

    I would say check the top cat shield its hidden if the top part is busted you can't easily spot it . Like mine http://hondakarma.com/threads/5421/
    yes mate manifold is a big job, there is a DIY guide for that on here have a look.

    Very helpful thanks. My cat guard is corroded and it sounds like you are describing my noise. I tried to weld the guard today still the same but I'm have a better look as I hadnt much time today. The fumes are only now and again on idle. Going to call honda tomorrow to see what they say.

    Had a better look today. The rattle seems to be linked to the manifold, the noise is around that area. I ruled out the cat cover. I'm assuming it's a manifold now. Another issue I have is the steering column buzzing is fix for it?
