ok title says it all i dont want the cool trend or the in thing i want bang for my buck! so i ask will my milage go up with a lass restricted exhaust?
dose it matter if it's duels or not? any and all help is awesome and appreciated thank all

 

Generally, no. Not in any significant or consistent manner.

MGD

 

Not so much...

 

only with a TB spacer!

 

Lol I think mine went down after I did my exhaust. I love the sound though it is worth it.

 

No, your MPG went down becuase it hard keeping the foot of the gas with those pipes roaring

 

Mine went up a consistent 2 miles per gallon city from 12.5 to 14.5 even when i step on it its still above 14 mpg
Highway went up to 18.5 Vegas to San Diego Trip and San Diego to Vegas @ 19.5 @75mph with 35's and 18's loaded inside and out but probably had a tailwind on the way back. Both ways was extremely windy, especially on the way there it was a head wind half the way.
Mind you I went ahead and did a full obx racing headers back custom exhaust, no highflows, resonators, but did an X pipe and 2 18" mufflers, all in all it was a good $1000 spent before install and piping.
This is all on an fx4 screw with a gryphon on canned tunes.
I will have efan on in about a month and hope to see a 1-2mpg increase city and 1-3mpg highway and maybe .5-2 on the custom tunes and hand calculated. The gryphon is within .4mpg reading of my actual calculated and the tires correct to within 1mph
Hope this helps!

 

MPG gain mods are retarded.

Say the exhaust did give you a 1MPG increase....Which it wont

But it cost a good average price of 350 bucks

How long do you think it would take to break even to get back 350 bucks in saved fuel? Years. And probably many more years than you would own the truck

People do thousands of dollars in mods for just 3 MPG increase when all is said and done with E fans and what not. DO you have any idea how long it would take to just cut even on 1500 spent? At least 15 years im whilling to bet

You will do the exhaust on your truck because you want it to sound better not because of any other gains. Because you wont see any

 

Hasked and i had some input to the question for comparison.
Let us spend our money on upgrades for mileage, sure in the long run it will cost a lot of money and we will probably never get the return on the expense vs mileage gained.

At least we can say we have a "cool" truck with an exhaust, or headers, or cooler a/c because of efan which came with a mileage increase.

The sound from the exhaust, the looks, smiles, nods and thumbs up are all worth it in my opinion. Especially when other people ask you and talk to you for endless hours about upgrades on the trucks they could do

 

Exactly. I do everything like exhaust to my truck to make it MY TRUCK. Some of the mods do give it 1MPG more. But I didn't do it for that. I did it for performance and to make it personalized to me

 

I am rather confused to where the heck your coming up with this assumption that mpg tools are retarted.

Lets say you get 10mpg and lets compare at driving a thousand miles

that comes out to 100 gallons of gas used because as you see
1000/10 = 100..
Which I am sure you can figure that out.. Let's say that gas costs an even 3 dollars.
3 X 100 = 300 dollars in gas

Lets say you now did a mod.. like you said.. it cost 350 dollars on whatever it may be.
1000 miles / 13 = 76.92 gallons of gas.
76.92 X 3 = 230 + 350 (for the mod) = 580

Now your 350 dollar mod paid off 70 dollars for every thousand miles. (incase you dont see why its because of this.

300 dollars at 10mpg for 1000 miles
230 dollars at 13mpg for 1000 miles

300-230 = 70
Lets say you drive on average as the normal person.. Isn't that 12 thousand a year?

12 x 70 = 840 dollars saved for 12 thousand miles
840 - 350 = 490


So in one year you saved 490 dollars. Now I know this is a bit extreme because 3mpg for 350 seems a bit unreal (if its possible tell me where and ill get it).

Say you do the gryphon cts with canned tunes bla bla bla and get 1-2 mpg increase (lets say 1, take the lower number to make it look less jaded.. their priced at 630 or so?) and spend 1000 dollars on the whole exhaust etc setup so we get 1-2 mpg more (as stated in prior post on this thread). Lets say you regear too because after your lift etc your tires cut down your mpg and we all need lifts.. Thats what 1-2k? (I haven't looked into prices on it so im clueless)

So now your saying
1000 + 630 + 1500 (went for middle number) = 3130
spent on three items which you save maybe 4mpg.

So lets start over..

10 mpg at 12 k miles a year comes out to 3600 dollars

at 14mpg with 12k miles you spend 2571

3600-2571=1028 saved in one year

In other words in 3.5 years you pay it off..

thats if you drive 12k. I go about 18k a year so for me cut off a year.

I understand that regearing isn't just a mpg mod but more so better for your truck with bigger tires etc and many other things.. In this example im using it as a mpg mod.

you said 1500 dollars. Instead of 3 I did 4mpg in my calcs and had a cost of 3600 dollars which atleast double the cost of what you said.. You were willing to bet 15 years to pay it off. With math I proved it took for someone like me little over 2 years.

Also if I did get 2mpg from the gryphon + 2mpg from the exhaust headers etc setup + 2mpg for regearing i would save 6mpg

Which means it would even take less time to pay off that cost..



If I just overwhelmed everyone with my numbers I apologize.. Hangovers and math dont go very well..

But seriously.. How do you figure 15 years?? I understand things like tires need to be replaced every 3 years or so.. But the 3 items I listed, I have hard time thinking the same..

 

would you mind repeating this

 

legorreta for the win.

 

oh gosh.. lol!

 

If you replace the exhaust manifolds with headers, you may notice a slight gain. Otherwise it will just make more noise
