The answer is likely, the muffler on you vehicle has two main intentions. Being the limiting of noise and usually act as some form of catalytic converter to limit pollution. However this action limits the flow of exhaust from the engine and thus increases back pressure decreasing the efficiency of the engine. The removal of it increases the power of the engine and could in fact thus also increase fuel efficiency.
most car designeers and engineers design vehicles to use the muffler to perform well. no, or little backpressure can cause engine failure. if it makes you feel better, remove it, but 99 out of 100 times there will be NO improvement, and if there is, its not going to be anything more than .1 mpg. so you wont save any money. and in most states it is very illegal.
This cant be answered as a simple yes or no. Its possible that the result can go either way.

How do I make my 1994 ford aerostar more fuel efficient?
Check your driving technique - SMOOTH starts and stops (never floor it), don't speed (higher speed = more fuel consumed), make sure your vehicle is as aerodynamically efficient as it can be - take it from an aeronautical engineer on that one!

Does removing a muffler help fuel mileage in a cummons 2005?
Having a free flow muffler will help improve fuel economy. In most mufflers on the market the air flow is by having the exhaust air take two 180 degree turns u turns. This restricts the airflow and causes immense back pressure. Having a straight through airflow muffler will improve mileage which is just like removing a muffler. By removing a muffler there is reduction in weight and improvement in back pressure. You may be cited for driving without a muffler, as it is required for noise control and pollution control.

How much money would it take to drive 175.9 miles?
It depends on the fuel efficiency of your mode of transport. Bikes, for example, are far more efficient that a huge car. Second, it depends on the type of fuel used and its cost.

The kerosene is a lighter oil. I think you would get more BTUs out of the heating oil. Just make sure that you are using the right fuel for the furnace that you have. Most now days would take heating oil.
What deo it mean for a hybrid car to be more efficient?
Honestly, lets go straight to the point. YES hybrids can get anywhere from 48 to 60 MPG allegedly. Which is 20% give or take, better than a small gasoline vehicle. Sounds good. But at the same time you are paying 30% more. I'm sorry, but in the long run (assuming fuel prices do not rise or fall drastically) the little fuel efficient car will pay for itself. TRUST ME. So when you ask, "what does it mean for a hybrid car to be more efficient?" the answer: ITS NOT.
