Eliminate exhaust restrictions and improve the sound profile of your first-generation Cummins with this Diamond Eye turbo-back muffler replacement pipe. This 4-inch diameter component is designed to replace the factory muffler section, providing a more direct path for exhaust gases to exit. By reducing backpressure, this pipe helps manage EGTs and improves overall engine efficiency during towing or heavy-duty use.

Constructed from high-quality aluminized steel, this pipe utilizes CNC mandrel bending to maintain a constant diameter throughout every curve, preventing the flow turbulence common in crush-bent alternatives. Specifically engineered for 2WD chassis configurations, it ensures proper clearance around factory drivetrain components for a straightforward installation.
