86 GL Exhaust Leaks, Hurting MPG?


 Share

Recommended Posts

Stock carbed 86 GL hatch back. I'm getting poor fuel economy, 16-18 MPG around the city, I don't drive it in the hwy.

 

I have a pretty rotten section of exhaust at the resonator, will this be hurting fuel economy? The rest of the exhaust is solid.

 

Thanks

Air pickup for the hvac is inside the front fenders. I've driven many of these many miles with exhaust leaks, never had smell in the car, or I'll effects. Small leaks, and ocasionally large. Locations range from engine to y pipe to muffler. Larger leaks get fixed faster, since noise. I'm pretty sensitive to smells, so I wouldn't put up with it except to get home with windows and vents open, for obvious safety reasons.
