Strangenoise from exhaust when cold ?

Hi

 

When my car is cold at about 3000rpm + my

exhaust sounds a bit tinny . This only happens for the first minute or so anyone have any ideas what it is ? Thanks for any replies.

Not sure but i always had a sound like a vuvuzela from my exhaust when cold...

If my exhaust sounded like one of those poxy things I'd of sold the car by now

Could be a slightly loose baffle that expands just enought to tighten itself when warmer ? do like richt does and just turn the radio up lol lol

you shouldnt really be ragging the car when its cold

3000 rpm is hardly 'ragging' it.

Or if your like me you sit in your car and chill out for 10 mins while it fully warms up

Glad I'm not the only one to do it

 

Get in the car 10/15 min before you have to leave, wait until the temp gauge it's just below or at half way and than drive away ( changing at around 2k for the first 10 min)

 

In relation to your problem........... Soryy I've no idea

Not wishing to open a can of worms here, but there is another chain of thought that waiting for the engine to warm up is a bad thing. The logic is that if the engine sits at idle then there is not much oil pressure which translates to low lubrication around the top of the engine. Therefore, driving the car, but keeping under 2-3k rpm increases the oil pressure and avoids this problem. I'm no expert, but that makes sense to me.

 

Regarding the noise, it definitely sounds like something loose, my K1 did this until warm - turned out to be a bung rattling.

Yeah i think i get the same noise too? The only way i can explain the sound is, its similar to the sound of an old Beetle Car(Herbie)
