Like you PORTHOS, my old car never did it which is why I'm noticing it now. I must admit it wasn't as bad when I filled up yesterday, started to get really noticable just under 70 where as it was from 50 the other day.
Yep sounds the same as mine, ha ha. I'll have a look later at it, but it is indeed over 50mph.
I do have a rattle on my exhaust that sounds AWFUL, you can hear it in the video around the 6 minute mark, it comes in at 3k and only just under. They are looking at it for me end of month 
Oddly though this one is far far better than my 160, that had too many problems to list including a leaking battery that destroyed 20% of the engine bay, lol.
Hi Porthos, was wondering if there are any updates on your rattly exhaust?
I noticed a slight rattle coming from the underneath of mine the day I picked it up, and then a couple of weeks later I heard it again, strangely when turning left?
On friday night I went for a blast to the coast and back, and the rattle is still there, it comes in at a very specific 92mph (thanks to the huge digital speedo!), I'm thinking its exhaust or heat shield?
Anybody else with similar problem?
Overall though, I am loving the sound it makes, getting more pops now too!. It genuinely makes me laugh how loud it is when on choke
