Can anyone tell me what roughly the gas mileage for a 99 cobra would be?
I average 18mpg city on mine, but I have a heavy foot and a header leak which might be throwing the 02 readings off a little.
FWIW - Believe the window sticker rated 'em at "17 city & 25 highway."
I average 23.3 with mostly highway driving on my bone stock 99
With my 01 with a 04 cobra rear with 355s, flowmaster catback, jlt cai, and predator 93 tune. I average 25 highway. 23 mixed with a/c. and all city about 17 which I never do.
