Will LT's solve the problem?
I keep getting a catalyst efficiency code. I filled my gas tank to see
how many miles I can get out of a full tank and I only got a 175 miles.
Is this a result of the catalyst problem? I also seem to have a lost of low end power. I ordered flowtech headers a month ago will these help?

How many miles did you used to get on a tank of gas? I have an A4 w/3.23's and I usually get 150 miles for the first 3/4 tank and less than 50 on the last quarter for a total of roughly 160-200 miles tops before I fill up again. I think I usually get 16 mpg at absolute best....... This is with in town driving with virtually no interstate and little highway and a lead foot. I realize it is running a little rich right now b/c of untuned headers and I get on it a lot because it sounds so nice but i've never got better mileage than that hardly anyway.

Yeah i would ditch those cats and get an ORY my 99 A4 W/3.23's got almost 300 miles to the tank when i drove it back from Texas I stopped one time for fuel in La. i think the average you should get is anywhere between 250-275 miles to a tankfull also be sure the fuel guage is working right they like to float hope this helps

i usually get 21-22 mpg (mixed interstate/city)
i got 20 mpg driving all interstate in 3rd gear (tranny problems)
i can get 300 miles on a tank easy and when the tank is entirely interstate,i have gotten 350+ miles. (24ish mpg)
I even get 18-19 romping it for a full tank
16 seems really low, you might wanna have that checked out
