A packed or baffled 4-inch muffler that has plugged up raises backpressure and exhaust gas temperature on a long pull. Replace it with Diamond Eye 460031, a T409 stainless straight-through muffler with a perforated core.

• Build: T409 stainless, perforated straight-through core, so exhaust keeps moving instead of dead-ending in a chamber.
• Part number: Diamond Eye 460031. 4-inch inside-diameter inlet and 4-inch inside-diameter outlet, 30 inches overall.
• Fitment: Universal 4-inch exhaust. Not a vehicle-specific kit.
• Does not fit: A 5-inch system, or a 4-inch system that does not have 30 inches of room where the muffler sits.
• Not in the box: The muffler only. No clamps, pipes, or tip.
