Does this help gas mileage...true or false ?

By installing a nice loud music to the ear cat back exhaust system to a new ride really help gas mileage improve ? Is there any written PROFF of that ? or is it all mind over matter ? With today's rides....I'm sure that ever drop of power is engineered into the muffler for noise reduction and performance...yes no ?

Hello Bob: I don't know about new cars in general, but Ford engineers say that the new Mustang is getting the best gas mileage possible and any changes will actually reduce gas mileage.

The SOUND emanating from your muffler cannot genuinely effect the fuel mileage of your car.

The Ease of Flow out the entire exhaust system is what can effect your mileage.

Sound is only a vibration of the air waves.

Hello back at you Calspec. What you say is much the same I was thinking, but I also think the computers makes changes to any mods that have been done to the ride.

Re: Does this help gas mileage...true or false ?

Although I dont have access to a dyno, there have been plenty of those who do. If we are talking only about a late model 2005 up Stang GT????? Who knows.... It may get less of a HP increase than say going from a restrictive 2 into 1 (such as my wifes 99 3.8) to a cat back true dual setup. I dont have "proof" IE Dyno results but the seat of the pants dyno says uhhhhhh yeah. I can feel a definite difference from the less restrictive single exhaust... and it isnt the sound waves either. The tires will break loose easier from a dead stop and it has more of the push you into the seat acceleration than before the cat back. Each car will obviously be different and how much exhaust IE... cat backs or full out from the head back, and how restrictive the original exhaust is in the first place....

Re: Does this help gas mileage...true or false ?

OK....I am half asleep apparently based on the previous response....help gas mileage?????????? If it increases the ability of the engine to breathe thereby increasing efficiency then it's a definate maybe... (not the answer you were looking for) but in my experience the rumble from the exhaust causes a medical condition known as foot drop or more precisely leadfootitis which definitely bad for gas mileage

Re: Does this help gas mileage...true or false ?

Ok i have this to say on the matter. I'm not an engineer by any means, but lets just do some math here.
If you spent say $700 on a cat back system, and a high flow K&N air filter and some special "wakadoo" fuel system device, are you really going to offset the cost of all those upgrades to justify 1 or 2 mpg?? It would take many years of driving to get that cash back.

If you drive say (like i do) 50 miles a day and average 20mpg. In a year of driving your going to spend $2340 on gas in that year @ 3.60 a gallon.
50 miles x 5 days a week = 13000 miles 13000 / 20 mpg = 650 gallons of gas x 3.60 a gallon $2340.

Now do that with 22mpg. Now you have $2127 for the year. a cost savings of $213. Not bad really. But depending on how you get that savings is how long it will take to recoup and actually SAVE money is something that needs to be looked at.

Also don't forget that the better it sounds or runs when we "have our foot in it" the more likely we will end up killing the gas mileage that we thought we were saving . ( I'M guilty!!)

The best way to save gas is drive like grandma.. sorry to say. My Focus is rated at 32 hwy and on a trip to my moms house thats a 100 miles away, i averaged 38. Well i never got it above 65 and did long easy acceleration runs to get there, and long easy stops. Plus using the cruise control as much as possible.
Sorry to say that i don't drive like that all the time. Most of the time i average 25mpg cause I'm in a hurry.

I say lets upgrade and do it like you want, but lets not try and justify mileage as the reasons.
While I'm ranting i also think that these hybrids are just ridiculous as far as gas mileage cost savings are concerned. Why? If they weren't being hyped up for initial cost at near $26,000 to $30,000 then id say "great! I'm saving money at the pump."

Cost of and escape hybrid per month 470 costing me about 5650 a year for payments and another 1370 for gas (@34mpg). I dont recall my Ranger costing even near 300 for the year maintenace. so im still way cost ahead driving my ranger even though i only average 22 -24mpg (heavy foot 4 banger).

YA i guess you could make a case for emissions and gas usage overall throughout the US that if we all drove Prius's wed be better for the enviorment ( so were told ) but then if we all did drive prius's then just give me the check please. Im OUUUTTA HEREEE!!!

Sigh sorry im done now.


Life long project. No it wont ever end....

It will make your mileage worse. If your like most people you'll always be on the gas to hear the music emanating from your new pipes.

Re: Does this help gas mileage...true or false ?

You can add things that will make more power, but that typically won't help mileage at all. And, nowdays - most of those things will allow the dealer to void your warranty should you bring it in with an issue. UNLESS it's a dealer installed do-dad. ESPECIALLY oil soaked air filters in front of the mass air sensor.

Re: Does this help gas mileage...true or false ?

I just saw on the news today an old guy that made some kind of switch for his cars and getting 41mpg from the one car and the previous car got 60 mpg. Not sure what it would do to a modern fuel injection car, maybe someone knows. Doesn't seem like it would be good for our carbed cars or injected to me.

Once you are up to 35 mph you flip the switch and it cuts off 4 of the 8 cylinders or 3 of 6 from getting fuel I guess. They didn't get into a lot of detail on that aspect but would assume that was what it does.

First Coast Man Invents Gas Saving Device

Article found at: http://www.firstcoastnews.com/news/l...storyid=101986

By Ken Amaro
First Coast News

JACKSONVILLE, FL -- Fred Craine has invented a gas saving device he calls "Mylege Mastre."

"It has never failed," says Craine.

Craine says his invention saves gas and reduces gas emissions.

Craine says, "I'm getting 42 miles to the gallon on this car (a 1998 Ford Taurus). On the other car, I got 60."

Craine is not an engineer, but has done mechanic work all of his life.

He says the electronic device is designed for fuel-injected engines.

At speeds of 35 miles an hour or better, he says you press a switch and the "Mylege Mastre" cuts off the fuel to half of the engine saving gas.

Retired engineer Dave Engle is Craine's friend and technical consultant.

"The secret of the invention is the simplicity and dependability of it," says Engle.

Engle is encouraging Craine to take the "Mylege Mastre" to market.

"I'd like America to use this device to reduce their gas bills. I don't want to take it to the oil companies because they will throw it away," says Craine.

Craine says his "Mylege Mastre" will sell for $35 to $70, depending on the size of the engine and if the vehicle has cruise control.

He says it works on any four, six, or eight cylinder engine and takes about an hour to install.

Craine plans to explore the possibility of registering his invention with the United States Patent and Trademark Office.

here is yet another different unit that american car manufacturers will never implement.

Cut off gas to half the engine ...must cut out the fire too... talk about lean burn........ possible I suppose with the right approach

If you can keep your foot out of it..Often times it equals better mileage. In the carb days it was like leaning out the carb which could equal better mileage.
