In general, ANY exhaust system upgrade that significantly lowers the backpressure of the exhaust system (by exhaust flowing through it more easily) will improve fuel economy. This can be done with a "single" exhaust, but is sometimes easier to do with a "dual". An advantage of the duals is that you can use two mufflers rather than one free-flow muffler. This can either provide extremely low back-pressure, or - if you choose - retain more of the factory exhaust sound with just a slight sacrifice in back-pressure (but still much lower than the stock exhaust). The two three main upgrades that you can do to improve fuel economy are, in order of easiest and cheapest first: switch your whole drivetrain to premium synthetic lubricants, upgrade (replace) your engine air intake system, and install a tonneau cover. Each of those is likely to improve fuel economy by 5 to 10% (assuming you choose your lubricants carefully). Here's a link to fuel economy tips and details on those three suggestions: http://www.ultimatesyntheticoil.com/Improve_Fuel_Economy/Increase_Fuel_Economy.htm
Yes, dual exhaust will improve milage. Then again just changing to a free flow muffler and the pipe from there out will also give a slight increase. A good cold air intake, like AEM has ( non-oiled dry filter) will also give an increase. Unfortunately a tonneau cover will not. The way pick ups are designed, a cover, dropping or removing the tail gate will create turbulance that will increase drag and therefore reduce milage. with the tailgate up it actually forms a bubble that helps air flow over the truck. Right now I drive a 2010 F150 FX4. The only thing I did so far was oil and filter. I put a K&N oil filter on it and put 6 quarts of Royal Purple oil and 1 quart of Duralube in it. On the interstate with the a/c on and cruise control set at 65 I am getting between 24.1 and 24.6 mpg. I would try this on your truck, or any other vehicle first. Second would be find a reputable shop and just have them do the back half of the exhaust. Try for 3 inch pipe to the muffler and a single in/dual out with 2 1/4-2 1/5 pipe out works fine. Single in/single out set up the same way will give about the same results.
A dual exhaust system & or headers will increase fuel mileage but only slightly. Not enough to recoup the expense of the systems.
where is the fuel pump rely on a 2005 f150 with a 5.4
yes you can on eBay too
yes they are basicly the same truck
i own a 2002 f150 and it has 196,000 miles and still runs great. Over 150,000 miles is considered high mileage on any vehicle. That does not necessarily mean there is something wrong with it.
Yes, they make performance chips for a F150. They will add performance and increase you gas mileage to get the most out of your engine.
It should i don't think they changed the width of anything tell 97
They are located on the exhaust right before the cats.
Just downstream after the exhaust manifold
On the Starter
Most oxygen sensors are in the exhaust pipe....between the exhaust manifold and the catalytic converter.
O2 sensors are always located on the exhaust system.O2 sensors are always located on the exhaust system.
It is very hard.
You can find listings for used Ford F150 trucks at autotrader.com and kbb.com under "Used Cars". The age, mileage, and condition of the used Ford F150 will dictate the price being asked by the seller.
A 2005 Ford F150 can be purchased from Edmunds used cars who currently stock that exact model. Kbb and the Autotrader are also two valuable places to check.
On your Ford F-150 ( V8 ) Bank 1 is the passenger side of the engine Sensor 1 is close to the engine before the exhaust enters the catalytic converter
Usually in the exhaust pipes coming off the manifolds
I can, yes. You? Try it and we'll see.
There usually on the exhaust header
