Question that's probably been asked alot.

If I take my muffler off will it hurt my MPG?

 

[Daves89]

I doubt it hurt it but I could be wrong and it's going to make your truck very loud. I get between 17 to 20 mpgs with my exhaust set up.

 

[koda6966]

Well it kind of fell off.. I just want to know how bad it will hurt my mpg before I get it put it back on.

 

[Daves89]

You should be fine
How long untill you get it put back on?

 

[koda6966]

Depends on how lazy I am really. I just need like a 5 dollar clamp and it will go back on just fine. I never have the time to do it though, so it might take a few weeks. Between work, college, and sleep there isn't much time to spare. I was just wondering how bad it will hurt my mpg in the meantime.

You wont notice a big change in the mpg. If your truck has a good tune up and you drive it right your mpg will be in the lower 20's. I would fill it up drive it for a couple of days then fill it again to calculate your mileage to find out for sure.

You will notice a Huge drop in MPG. And the sound is quite awful.

Oh, as well as a Huge drop in power. That more than anything else.

I only get about 19 on a good day now. My gearing is wrong for my tires. I'm supposed to have 215-70R14's on it. I'm running 235-75R15's in the front and 225-75R16's (I think. Might be 70's) in the back until I get my new tires in the front to match the rear.

Somehow I doubt that. I ran my truck with half a muffler (don't ask) for about two years.

Sometimes you can notice a SLIGHT loss in power. More of a (MINUTE) loss of power. That is only cause the engine loses some back pressure without the muffler. As for MPG, should stay they same. The cat being clogged or a bad O2 sensor about the only thing on the exhaust that will change your MPG for the worse.

thats funny considering when my muffler was off, i didnt notice any drop in anything, only increase I got was sound. I'm straight piped into duals right out the back of my ranger, had it like that for almost a year. theres no "huge" drop in anything

Theres that term again. you won't lose any power from no muffler, the engine shoudl get all the "back pressure" it needs before the muffler anyways.

Why did the muffler fall off anyways? Rusted?

Time for a cheapy new one?

and only 19mpgs? What gearing do you have?

A clamp fell off. Must not have been tight enough. And I have the wrong gearing. Can't remember what it is, but it's low. Like 3.14 or something. I need an upgrade.

stock ranger gearing is 3.08 or 3.45, you probably have the 3.08

 

[koda6966]

I think it was the 3.45, that sounds about right.

 

[Original_Ranger84]

Dang I don't think I could handle those gears with my 31's... I get 19 city and 25 highway, But thats still a bit odd, those tires arent massive you should be getting atleast 20 -22 i would think.

You clamped it on? You should just get one of the pipe connectors and weld it on. problem solved.
