Diamond Eye 560031 – 5" 409 Stainless Steel Perforated Performance Muffler (30" Overall)

Upgrade your diesel truck’s exhaust with the Diamond Eye 560031 5-inch 409 stainless steel high-flow muffler. This straight-through perforated design delivers strong airflow, reduced backpressure, and a deep, aggressive exhaust note while helping control excessive drone and rasp compared to a full straight pipe.

Key Features

• Constructed from durable T409 stainless steel for excellent corrosion resistance and long service life in daily-driven or hard-worked diesel applications
• Straight-through perforated core packed and wrapped in stainless mesh and fiberglass for high flow and controlled tone
• 5" ID inlet and 5" ID outlet (center/center configuration)
• 30" overall length / 24" body / 7" round case
• Universal fit for most aftermarket 5" diesel exhaust systems (Cummins, Duramax, Power Stroke, and custom builds)
• Natural finish
• Made in the USA

Benefits

This muffler is engineered to improve exhaust flow, support better throttle response, and help lower EGTs in performance-oriented 5" systems while still providing a refined, aggressive diesel sound. Ideal for turbo-back or cat-back setups where maximum flow and durability matter.

Installation Note: Designed as a universal straight-section muffler. Can typically be welded or clamped into place on 5" tubing (band clamps recommended for non-welded installs).

Warranty: Backed by Diamond Eye’s 6 Year limited warranty on stainless performance components

Perfect for diesel owners looking for a durable, high-flow 5" muffler that balances performance and sound without the harshness of a full delete.
