I've got a 91 turbo with stock exhaust. Its leaking behind the muffler. How bad is this for fuel mileage ? I ask cause I've been getting 400KM's per tank for the last couple of years now..?
I did the spark plugs air filter and fuel filter in the last 6 months.?

Exhaust leaks post O2 sensor don't matter very much.
Over the summer, I ran open downpipe almost more than with the rest of the exhaust, and got around 13mpg.
What spark plugs did you use?
