The MBRP Exhaust S6150409 is designed for 1988-1993 Cummins 5.9L trucks equipped with 4WD. This system features a full 4-inch turbo back design, which replaces the exhaust from the turbocharger to the tailpipe. Because of this, it provides a complete upgrade over the factory exhaust system while maintaining proper fitment.

4 Inch Turbo Back Exhaust Design

This system uses a 4-inch diameter exhaust layout, which supports improved exhaust flow from the turbo outlet through the entire system. In addition, the turbo back configuration replaces restrictive factory exhaust sections. As a result, it provides a straightforward solution for improving exhaust efficiency on compatible trucks.

T409 Stainless Steel Construction

The MBRP Exhaust S6150409 is constructed from T409 stainless steel, which is designed to handle harsh road conditions. In addition, this system is part of MBRP’s Armor Plus series, which provides a balance between durability and cost. Because of this, it offers a budget-friendly entry into stainless steel exhaust systems while maintaining strength.

Heavy Duty Design with Included Tip

This system includes welded-on hangers for installation and a 5-inch outside diameter T304 stainless steel tip. The single side exit configuration provides a clean layout while maintaining proper exhaust routing. In addition, the heavy-duty construction supports long-term use in demanding environments.
