I found with an old 1992 Honda Accord that when I changed out the muffler for a performance one, my mileage increased by 5-8 MPG. I guess less back pressure helped on performance and fuel economy. I don't have mufflers to sell, but it may be something to consider.

Only way these do it is to modify the A/F mixture which changes the emissions in a bad way. Best thing to do is reduce friction and make the fuel burn better. Has anyone played with the bottom side to reduce the rear bumper scoop action??

What material did you use and how did you fasten it. I was thinking that the front should go over the torque tube/frame and move with it and the rear should be on the bottom of the lower skirt. My only concern is the air flow from the wheel wells is a little screwy if it goes in then it would be above the pan . . .
Did you notice any improvement at higher speeds?

im only getting 21 highway
i dont know if i got a bad tank of gas or what
i do have my tires under inflated, im going to fill them up and see if it makes that much of a difference
whats the perfect PSI?

If you like to turn fast in corners then a little extra pressure will keep you from squeeling the tires and rolling over on the side walls. I run 38 psi front and 37 rear and yes it is a little hard but it rolls nice and I have never heard my tires squeel - try 32 PSI for a start and 21mpg is WAY TOO LOW. Check for a gas leak and make sure you lock the gas door!! Usually I have to check the tire pressure and add a few pound every other week so if you don't check them more than a few times a year you are definately under inflated and loosing a lot of air. It helps to get a good tire pressure gauge - the savings in gas over the life of the car will easily pay for it. You don't have to spend a lot but I nice dial gauge that looks well made or a digital one is a great investment.

If you do get a new air gauge go for one that has a dial as suggested as they are easier to read, also some will hold the air pressure reading so you don't have to have your head in the dirt to see what it says those usally also have a built in bleed valve that you can press to let out the air slowly ..last on I got was between $15-20 and was pretty nice but for under $10 you should find a good one...there are tons of articles on how air gauges are all "off" but my best suggestion is find one you like and use the same one every time so at least all your tires will be off equally! You will get a feel for pressure changes after a while and how it affect handling and mileage.

Don't know but I change it every 5,000 when I get near to that mark the engine seems to tick a bit more at idle and the mileage goes down maybe with the deposits it picks up it makes it thicker causing more resitance we are running a thin oil..?

Hopefully this will have further positive effect on my mileage. I'll be checking them weekly from this point forward.

--if you guys ever go to the races most of the major tire manufactures will have a pressure check where you can see how far your gauges are off just bring your gauge in and ask them, this way you can mark on your gauge where say 30psi is in relation to the marks...the digital gauges are cool cause they are super easy to read!
