Does removing your muffler improve gas mileage?
Translating Jeff’s reply: Removing your muffler will likely reduce mileage and power, not improve it.
The only thing that you will gain is noise.
Not quite, you will get more noise, but there will be a small increase in MPG and peak power..
Why is straight piping illegal?
19 Straight Pipes There are a few reasons as the why this is illegal. The first being the obvious for noise ordinance. The second being emissions, which in some states is tougher to get around as its required to be checked annually in order to pass inspection and register or insure your vehicle.
Does a loud exhaust use more fuel?
Louder exhaust does not use more fuel. In fact- there’s no correlation between them. A car engine creates combustion to deliver power – which generates a lot of noise. An exhaust system is equipped with a muffler to reduce this noise.
Is 2.5 or 3 inch exhaust better?
yes 3″ probably better, but might be hard to run all the way to the back next to the tank, if your using the smaller TTi headers i don’t think the 3″ would give much more HP, you could also go 3″ to the muffler and 2.5″ out the back.
Can you undo a muffler delete?
Absolutely. You’re simply replacing the muffler with pipe. Easily reversed.
Are True Duals louder than single?
The duals will be just about be louder in every acceleating scenario but the idle will be louder with the single exhaust due to the stronger pulsation.
Does straight piping increase horsepower?
A straight pipe exhaust will reduce the amount of pressure that is put on an engine by exhaust gases, which will let an engine function better overall. You’ll see an increase in both horsepower and torque when you put a straight pipe exhaust into place.
How much HP does a muffler delete add?
So for most cars, the muffler delete will not add any power. Some cars will gain some power, but generally it’s not much, usually under 5 horsepower. However, if you have a car modified for more power, and still has the stock mufflers, then you’ll have more gain.
Can a muffler delete ruin your car?
no it doesn’t cause damage to the car. your car will perform the same. it doesn’t improve performance. if your car sounds good without mufflers, take them off.
Do you lose torque with straight pipes?
No it won’t. That’s a myth. Changes in the a/f and loss of exhaust velocity will affect torque.
Can you pass emissions with a straight pipe?
Straight pipes as in no cats or straight pipes as in no mufflers? Mufflers are not a smog check item, anything behind the catalytic converters on the car are not considered emissions components and can be changed at will. (As long as you stay under the sound limits dictated by local ordinance…)
Does straight pipe hurt your engine?
… a race car style exhaust system is a bad upgrade for a street vehicle. … A straight pipe, for example, can cause exhaust gas velocity to increase. This will likely reduce engine performance below 2,000 or 2,500 RPM, making your vehicle a little slower to launch from a stoplight.
