Anyway, most of my other issues are out of the way so it's time to reaffirm my lurrve for my Prelude. However, this interesting sight has appeared over the past couple of weeks and would like an opinion on what you think it is.
As you can see from the photos ( pretty poor I accept, they're from my phone) I have a lot of black 'dust' that is appearing in the 'cones' (is that the right word?) and also all on the rearmost part of the back box itself.
I've never had it like this before and am wondering what it is. A couple of weeks ago I drove to Singapore with not a problem and when I got back the exhaust did not look like this. I use RON97 Shell petrol normally however, on my trip to Singers I filled up twice with the Shell V-power Racing petrol. I'd also put a bottle of Sonax injector cleaner into the tank about 3 weeks ago.
Like I said, I've never seen my exhaust pipes and back box so dirty with this 'powdery/sooty' stuff. I've felt it and it's not oily, just like a kind of dust. I'd love to hear your thoughts gentlemen. Anyway, here's the shots, interstingly enough, I cleaned the car on Monday and have only been tootling backwards and forwards, so this 'soot' you see here is 48hrs after I'd cleaned it.
The dust settling on the lower half of the cones

Apologies for crappy quality but you can see the dust/soot on the lower halves of the cones.

Here's the back box - this after being washed 48hrs ago.

For a clean freak like me this is heartbreaking.

I'd be so very grateful for any pearls of wisdom from your collective brains. Thanks gents, Simon.
