Loud Muffler

Generally speaking, all performance mufflers are louder than stock mufflers. Among performance mufflers some could be louder than others.

How could we tell?

If you are looking for a quiet performance muffler, here are a few clues:

1. The muffler has a smaller outlet

2. The muffler has NO sliencer

(A Twin-Loop Chamber muffler is usually quiet because of its construction).

However, if you are looking for a louder muffler, here are the features you should take a note:

1. The muffler is shorter in body length

2. The muffler has a bigger outlet

3. The muffler has a silencer installed

Take the silencer off, the muffler could get really loud.
