A 30-inch 4-inch muffler that has packed up is a long restriction, not a short one, and a 26-inch muffler will not fill the hangers. Replace it with Diamond Eye 460005, the 30-inch aluminized louvered muffler.

• Build: Aluminized louvered straight-through core, 30 inches overall, so the gas path stays open without fiberglass packing.
• Part number: Diamond Eye 460005. 4-inch inside-diameter inlet and outlet. The 26-inch louvered muffler is 460002.
• Fitment: Universal 4-inch exhaust with room for 30 inches.
• Does not fit: A 5-inch system, or a 26-inch muffler pocket.
• Not in the box: The muffler only. No clamps or tip.

Order today to secure your replacement and measure the old muffler. Order 460002 if that span is 26 inches.
