Kgrant Posted November 22, 2016 Share Posted November 22, 2016 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 Link to comment Share on other sites More sharing options...

BEECHBM69 Posted November 22, 2016 Share Posted November 22, 2016 I doubt it would hurt fuel economy, but it could greatly reduce your lifespan. Unless you're driving with your window open, you need to get that addressed. Dan Link to comment Share on other sites More sharing options...
Kgrant Posted November 22, 2016 Author Share Posted November 22, 2016 Kinda odd but I don't get any exhaust smell in the car. Link to comment Share on other sites More sharing options...
DaveT Posted November 22, 2016 Share Posted November 22, 2016 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.
