⚙️ Performance Benefits:

Factory diesel exhaust systems are often 3″–3.5″ in diameter, which can restrict exhaust flow. Diamond Eye’s 4″ muffler systems are engineered using CNC mandrel bending to maintain consistent pipe diameter, allowing exhaust gases to exit more efficiently. The result is lower EGTs, improved throttle response, and better overall performance.

🛠️ Installation Notes:

• Includes required clamps, hangers, and mounting hardware

• Pre-configured for easy installation

• Typical install time is just over one hour

• Professional installation recommended

If you’re looking for a simple, effective exhaust upgrade that improves sound and performance without the cost of a full system, the Diamond Eye 4″ Muffler Kit is a proven solution for your OBS 7.3L Powerstroke.
