Diamond Eye 4in SS Y MFLR DEM400-P-SS-Y

This is a Diamond Eye 4-inch Y-pipe muffler, built for performance diesel exhaust systems. It's constructed from 409 stainless steel, which is a solid choice for exhaust components because it offers good resistance to corrosion and heat, helping it last longer in tough conditions.

Diamond Eye uses CNC mandrel bending for their tubing, which means they can bend the pipe without collapsing the diameter. This helps maintain smooth airflow through the exhaust system, which is important for performance. The perforated core inside the muffler is designed to manage exhaust sound while still allowing gases to flow efficiently. This Y-pipe configuration is often used to split an exhaust stream into two outlets.

Keep in mind that this part is not CARB approved and cannot be shipped to California. Always check local regulations regarding exhaust modifications.
