Vauxhall Astra mot advisory notice

Car: Vauxhall Astra
Variant: 1.4 16v
Model Year: 2003
Categories: Engine & Drivetrain
My car just passed it's mot but I got an advisory note saying, rear exhaust system has part of the system slightly deteriorated, should this be a big problem and get worse if left or should I just leave it, the other thing is I used to get 30mpg now I get 20mpg urban driving could this exhaust problem be to blame, thankyou for any suggestions.

If car just passed MOT , emissions should be o.k . You will see a decrease in mpg due to cold weather and car taking longer to warm up ,using gears more due to conditions .Exhaust can't be that bad if just an advisory .
