    Exhaust blowing out noise, but no holes?

    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...

    Seems it's actually blowing out of the turbo itself. The area round the actuator lever is black as my boot.

    New turbo time soon, I think.
