A 5-inch system that still runs a small or plugged muffler gives the extra pipe diameter back at the worst spot. Replace that muffler with Diamond Eye 560031, a 409 stainless straight-through muffler with a packed perforated core.

• Build: 409 stainless, perforated core packed and wrapped in stainless mesh and fiberglass, so the 5-inch flow stays open while the packing takes the edge off an empty pipe.
• Part number: Diamond Eye 560031. 5-inch center inlet and 5-inch center outlet. Body is 24 inches inside a 30-inch overall length. Round case, natural finish.
• Fitment: Universal 5-inch exhaust with room for a 30-inch muffler.
• Does not fit: A 4-inch system, or an offset inlet and outlet.
• Not in the box: The muffler only. No clamps or tip.

Order today to secure your replacement and confirm you have a center-in, center-out 5-inch muffler location and 30 inches of length.
