These are neat little mufflers. Super compact design.  These are friction fit, and cannot use clamps.  One side will slide onto 1.5" pipes, while the other will accommodate 1.75".  The mounting bracket is what will hold it in place.

• Mounting bracket included
• Mounts on left, or right side.
• Super small, compact design means minimal back pressure which also means big sound!
