Reducing muffler length usually results in nothing more than more noise, without much loss, and certainly no gain in performance as a result . It can have an effect on performance, but usually, the entrance to the muffler serves as the effective end point of the exhaust system.

Does muffler affect engine performance?
Mufflers’ Effect on Performance
An engine is able to generate more power, faster if it is able to get rid of all of the exhaust gases it produces quickly. By their nature, mufflers restrict exhaust flow or create back pressure, which slightly slows down your engine .
Is a shorter exhaust better?

Can an exhaust be too long?
Registered. Yes, it is possible for exhaust piping to be too large . When the pipe diameter increases, the exhaust gas velocity decreases and can be detrimental to engine performance. As you are aware, another drawback of tubing that is too large, is increased noise.
Is a longer muffler quieter?
Generally, the more volume, the quieter it will be . You have to compare similar designs, however. A big straight through design, e.g. most fiber packed mufflers, isn’t going to be as quiet as a baffle type muffler, e.g. most stock mufflers.
What sounds better 2.5 or 3 inch exhaust?

Does longer exhaust make it quieter?

Do mufflers reduce power?
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.

Do exhaust pipes need to be the same length?
Bottom line, yes, the pipes should be the same length . Here is whatthe article says: “Assuming that an exhaust system is otherwise properly designed, equal length pipes offer some benefits that are not present with unequal length pipes.
Is 4 inch exhaust too big?
The general rule of thumb for exhaust systems is, as we said 3-3.5in for 250-350whp, above that 4′′ exhaust is the right size , but that’s about as big as you want to go, even at the 400whp-500whp level.
Does a 3 inch exhaust make a difference?

Does a bigger 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 a bigger muffler better?
The more exhaust your engine produces, the less the gas expands. The less it expands, the less it cools, and the faster it goes. So, basically, bigger exhaust means more power at high RPMs, and less power at low RPMs .

If you are too lazy for the details, bigger exhaust pipes do make the exhaust louder – but only by a little . Exhaust pipes are made bigger to allow better exhaust flow. This is important for increased performance and horsepower (not for the sound).
Will a Flowmaster muffler increase horsepower?
Less restrictive performance mufflers, such as Flowmaster 10-Series , along with the removal of resonators can yield an increase of up to 15-horsepower at the wheels . Removal of all mufflers and resonators will provide slightly greater increases but remember as the restrictions are removed the exhaust grows louder.
Is exhaust worth upgrading?
By improving the airflow through the system and decreasing back pressure, aftermarket exhausts reduce the energy wasted in the system having to overcome these pressure problems . This leads to better fuel efficiency. Better sound: Aftermarket mufflers can significantly louden the sound of your engine.
