So I replaced the rusted out resonator and muffler over the weekend. The car is MUCH QUIETER NOW,
I drove to work this morning and my MPG jumped to 61.2 MPG?! My previous best commute to work was 55.6 mpg.
I did use the kill switch a couple times during the commute, but not enough to total a 5.2 mpg gain.
I wonder if a broken exhaust greatly affects mpg?
**SIDE NOTE: I discovered there is a rear sway bar installed too!**
