Will an overland exhaust improve mpg on 2019 4 runner?
I switched out my OEM air filter for an S&B then replace oem exhaust with a
Magnaflo Overland exhaust.My mileage estimator is guessing at 15.9-16.00
mpg.I'm not even getting to 300 miles per fill up.What tha hell? My driving style
has not changed,mostly just poking along.I may put the oem air back in.What
about the Magnaflo? It run's great! Mileage is uninspiring.
