Yep Matt :glasses7: taking the potatoe out of the exhaust sure makes a difference
I watched a freind drive on a parking lot at work one early morning
and his catalytic converter was glowing red, I told him and he said his mpg has went WAY down (driving 60 miles to work each day) he
replaced it and grained 10 mpg he said. It was a 84 Monty Carlo.
