MBRP S6150P 4 Inch Turbo Back Exhaust

MBRP S6150P 4 Inch Turbo Back Exhaust for 1988–1993 Cummins

The MBRP S6150P 4-inch turbo back exhaust is designed for 1988–1993 Cummins 5.9L trucks that need improved exhaust flow and a stronger exhaust tone. This system replaces the factory exhaust from the turbo back and reduces restriction throughout the entire system.

As a result, the engine moves exhaust gases more efficiently and responds better under load.

Turbo Back Exhaust Flow

This system replaces all piping from the turbo outlet to the tailpipe. Because of that, it removes factory choke points that limit performance.

In turn, exhaust gases exit faster, which helps maintain consistent performance during towing or daily driving.

Aluminized Steel Construction

MBRP builds the S6150P using aluminized steel. This material keeps costs down while still offering solid durability.

In addition, it performs well in moderate climates and normal driving conditions.

Two-Piece Tailpipe Design

This exhaust includes a two-piece tailpipe configuration. That design simplifies installation and ensures proper fitment on multiple truck configurations.

However, this system does not include an exhaust tip, allowing you to choose your preferred finish.

Sound Characteristics

This system includes a smaller muffler compared to higher-end kits. Because of that, it produces a more aggressive and raw exhaust tone.

It delivers a noticeable sound upgrade over stock without being completely open like a muffler delete.

Installation and Fitment

The system installs using factory mounting locations and OEM-style hangers. Therefore, installation remains straightforward with basic tools.

This kit is designed for 4WD trucks only.

Performance Benefits

Upgrading the exhaust system improves both sound and efficiency.

You can expect:

• Reduced exhaust restriction
• Improved throttle response
• More aggressive exhaust tone

Warranty Coverage

MBRP backs this system with a 1-year warranty on aluminized steel performance series systems.

Fitment

• 1988–1993 Dodge Ram Cummins 5.9L
• 4WD trucks only
