Heres the sound of modified stock muffler

Is the Apex muffler the same?

Yes basically the same the materials are a little lighter but the gutting is the same procedure.

It does sound good, I did my attak as well. Same sound. I only took about 3" out of the middle of the tubes and pulled the packing material out of those tubes.
