Fuel mileage and gutting cats
I have a 95 F150 300-6cyl and auto tranny. I put a 160 thermostat in it and I think my mileage dropped alot. Should I go back to a 180 or 195 degree thermostat? Also, I thought about gutting my cat for better exhaust flow. My state doesn't have emissions. Any advice would be great. Thank you.
