Car spec as in sig. Just short of 48k on the clock, and running the factory fit exhaust.
As per usual, the factory fit exhaust is starting to rot a bit round the back box (they always go at 4 years old near enough to the month).
However, I'm getting a bad noise as if the exhaust is blowing out, but I've checked very carefully underneath with a torch and there's no blowouts in the exhaust. I also get a smell of smoke under hard acceleration (considering the reek coming out the back that's not surprising really).
Could it be something at the turbo? I can't see under the heat shield to check under there. It's odd that I can't see any blowouts along the exhaust yet it's definately blowing out somewhere...
