MBRP S6100SLM 4 Inch Turbo Back Exhaust

MBRP S6100SLM 4 Inch Turbo Back Exhaust for 1994–2002 Cummins

The MBRP S6100SLM 4-inch turbo back exhaust is designed for 1994–2002 Cummins 5.9L trucks that need better exhaust flow and a more aggressive sound. This system replaces the entire factory exhaust from the turbo back, removing restrictions and improving engine efficiency.

If you want a louder, raw exhaust tone without a muffler, this system delivers exactly that.

Muffler Delete Design

This system comes standard with a muffler delete. Because of that, exhaust gases exit faster and with less restriction.

As a result, you get a sharper throttle response and a noticeably louder exhaust note.

409 Stainless Steel Construction

MBRP builds the S6100SLM using T409 stainless steel. This material resists corrosion better than aluminized steel while keeping cost reasonable.

In addition, it holds up well in daily driving conditions and moderate climates.

Turbo Back Flow Advantage

A turbo back exhaust replaces all piping behind the turbo. Therefore, it eliminates factory bottlenecks and improves airflow across the entire system.

That improvement helps the engine operate more efficiently under load.

Two-Piece Tailpipe Design

This system includes a two-piece tailpipe configuration. Because of that, installation becomes easier and more manageable.

However, this kit does not include an exhaust tip, allowing you to choose your own style.

Performance and Sound Gains

Upgrading to a 4-inch system changes how your truck performs and sounds.

You can expect:

• Increased exhaust flow
• More aggressive exhaust tone
• Reduced restriction under load

Installation Notes

This exhaust installs using factory mounting locations. No major modifications are required.

Always confirm fitment before installation.

Warranty Coverage

MBRP backs this system with a limited 5-year warranty on T409 stainless steel products. This covers defects in materials and workmanship under normal use.
