The 45 Series is our smallest muffler, at only 4.5" in diameter it is best used in a resonator position as it locks the internal volume to control low to mid frequencies. This model can effectively take the edge off a high pitched exhaust note but for meaningful  sound suppression, it is best paired with a larger unit in the rear.

Available in the following configurations and sizes:

• Body Length: 10", 14”, 18”, 22".
• Configurations: Center/Center.
• In/Out and Core Sizes: 2”, 2-1/4”, 2-1/2”, 3" and 3-1/2”.
