Big leak in my exhaust

Post by turbonator »

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?
2009 Outback 2.5XT. 5MT. Satin White Pearl.
2009 Impreza 2.5i Premium. Blue.
