Fiberglass packing in a 4-inch muffler burns out and then the core plugs, which puts the restriction back in a system you already opened up. Replace it with Diamond Eye 460002, a 26-inch aluminized louvered muffler with no packing to burn.

• Build: Aluminized louvered straight-through core. Louvers pass gas without a fiberglass pack, so the muffler does not rely on packing that can blow out.
• Part number: Diamond Eye 460002. 4-inch inside-diameter inlet and outlet, 26 inches overall.
• Fitment: Universal 4-inch exhaust with 26 inches of muffler room. The 30-inch louvered muffler is 460005.
• Does not fit: A 5-inch system, or a 30-inch muffler pocket.
• Not in the box: The muffler only. No clamps or tip.

Order today to secure your replacement and measure the muffler length. This one is 26 inches, not 30.
