it doesnt make any noticeable difference at all with fuel economy man. BUT its does make it sound better. makes you feel just a little bit cooler too.

You may get like 1 or less mpg and more power. What helps the most to save gas is driving habits.

the only way exhaust will effect your fuel mileage is if you converter is bad, bad being clogged or broken, and that only pertains to 96 and newer vehicles OBD II that have a down stream O2 sensor

when you go to flowmaster's, magnaflow's or anyone else's site and it says it adds so many hp, what they are not telling you is they are testing their exhaust systems on built motors ....on a 3L ranger only thing it will do is give it some sound. and if you open it up 2 much and relieve to much back pressure u can actually lose HP and TQ

A full catback exhaust will add decent power because you have mandrel bends and a free flowing muffler. The thunderbolt Ranger made more power with its Roush intake and exhaust. Just chopping the muffler off and putting in a crapmaster will make noise but that's it. Chopping a cat off will sound cool but you will lose power because you lose backpressure.

that is a cat back on a performance enhanced truck you are talking about not a bone stock 3.0 .... now if he was to do a cold air intake, exhaust, and some other minor bolt on mods yea it can and will help HP and fuel mileage

All the vehicles I see that are being tested are stock. Just look at Magnaflow's website and you will see stock vehicles in the videos.

my exhaust gave me 10hp gain. I know cuz it said so on the box. My cold air intake gave me 15hp. My programer gave me 18.
(Note all above numbers were pull right out of my rearend)

Now if all boxes were right and told the truth that would be a total of 43hp. If that truck gained 43hp I'm freaking hugh heffner!

No its not. When I took mine off all I saw was restrictive crush bends. Ford would not spend the extra money for the mandrel bend tubing just for a Ranger. Maybe if it was a special high performance model like a gt500 or GT but not on a plane jane Ranger. Hell they don't even give you doors on extended cabs as standard equipment.

I had crappy bends on my stock one too. I agree that not putting doors on extended cabs as standard options is lame. I would of had an 04 instead of the 99 but the 04 lacked the rear doors and i said screw that

When i did my exhaust I got better power. Mileage may be a little better but my converter was clogged. I also did a cat back and it was worth it.

Where I got my biggest gain in MPG was when I slowed down to 55-60. I went from 18 to 20 MPG. I also tried the coasting to lights and that other stuff. It really mellowed my stress level too. I like driving slower now. Remember: the president says to keep your tires inflated.

Behavior beat out the mechanics. But the mechanical stuff did get me more power when i wanted it. That alone was worth the $$.
