This has been getting worse as time goes on back in late July I changed out the plugs and wires thinking I would get better gas mileage. Wrong. It has progressively gotten worse from like 320 miles to a tank to like 280 and now it flucuates from 220-260 since I got flowmaster mufflers installed. Any suggestions on what to do. It's really starting to get increasingly annoying considering gas is about to go up again.

#1 - Change the fuel filter!!!!
#2 - My fuel mileage has always dropped for a while after I changed a part of my exhaust. Not because of the exhaust, mind you, but because I didnt shift as early as I used to. I just wanted to hear the sound of the exhaust. When I did the cat-back, I found myself turning down the radio at stoplight just so I could get on it. After a month or so, that got old, but then again after I did the LTs and the O/R X I did the same thing. Are you doing this? That will cut an ass load out of your MPG, I dropped from 280 miles on a tank to almost 220, but after I would quit, right back up to 280.
Just my .02 tho......

would that be confused you were banning
I'd say give it some time. I think mine dropped too when I first put in Borlas. Also, check your tire pressure. Make sure you're not running on 20lbs. or something.
Edit: Or maybe you were real lean back then where you were getting 320. You had a CAI to get the air in but no exhaust mod. Only time I (5speed 04 gt) get above 300 on a tank is on a road trip. Generally, I am around 260-280 per tank. Just got a tune, so I'm going to be checking again.
