Diamond Eye ELBOW 4in 90-DEGREE AL 431-410

This is a 4-inch, 90-degree aluminized elbow from Diamond Eye Performance. It's designed for performance diesel exhaust systems, giving you a clean way to make a tight bend in your exhaust routing. The aluminized steel construction offers good resistance to corrosion for everyday use.

Diamond Eye uses CNC mandrel bending to create these elbows, which helps maintain consistent pipe diameter through the bend. This is important for exhaust flow, especially in performance applications where every bit of efficiency counts. The 4-inch diameter is a common size for many diesel trucks, and the 90-degree angle allows for sharp turns when needed for routing.

Keep in mind this part is not CARB approved and cannot be shipped to California. It's a straightforward component for custom exhaust work or repairs where a specific bend is required.
