Diamond Eye 4in SS 90* ELBOW

This 4-inch, 90-degree elbow is made from 409 stainless steel, a solid choice for exhaust work because it holds up well to heat and corrosion. Diamond Eye uses CNC mandrel bending for these pipes, which means they maintain a consistent diameter through the bend. This helps keep exhaust flow smooth, which is important for performance, especially in diesel applications. It's a straightforward component for custom exhaust setups or repairs where you need to change the direction of your exhaust pipe by 90 degrees.

The 409 stainless steel construction offers a good balance of durability and cost for exhaust components. Mandrel bending is key here; unlike crush bending, it prevents the pipe from collapsing or restricting flow at the bend, ensuring your engine can breathe easier. This elbow is a common part of custom exhaust systems, particularly for diesel trucks where exhaust flow and heat management are critical.
