With clogged cats I got 12-15mpg. When i swapped in the O/R x-pipe it jumped to 20-25mpg.

if you have a odometer just take the mileageyou get in a 1/4 dividied by 3.85(the gas in a 1/4 tank and your set......), this is based on a 15.4 gal. tank which all mustangs should have stock, or at least i think
Bad idea, leaves a lot of area for guesswork. Do this instead: Fill it all the way up (to a specified point, like when it clicks off 3 times). Reset the odo at that point and drive. When you fill up again, fill up to the same spot (3 clicks off or whatever you decide), and divide the number of miles on the odo by the amount of gallons you put in. Most accurate way

I have dumps as of now, with no cats, I have to get a catted h or x pipe, I have been looking, pricey, trying to find a used one, but, then again that could be a waste of money if the cats are no good. Emissions blow, and no, I am not going to move to another state either, j/k.

Yeah true, but it cant be too far off really, I mean your specifcally filling to one point, and then diving it by the numberof miles you drove on the 1/4, i just dont understandwhat this "guesswork" is you speak of?
