MBRP S6026SLM 4 Inch Filter Back Exhaust System No Muffler Single Side Exit Stainless Steel

The MBRP S6026SLM is a high-performance 4-inch filter-back exhaust system engineered for 2007-2010 Chevrolet Silverado and GMC Sierra 2500/3500 trucks equipped with the 6.6L Duramax LMM engine. This single side exit configuration features no muffler for maximum exhaust flow and an aggressive exhaust tone that lets your diesel engine breathe freely.

Construction and Materials:

Part of MBRP's ARMOR PLUS Series, this exhaust system is constructed from corrosion-resistant T409 stainless steel tubing. All tubing features mandrel bending technology, which eliminates restrictive ripples in the bends and ensures smooth, uninterrupted exhaust flow. This superior construction allows more fresh air into your engine's cylinders, resulting in improved horsepower, torque, and overall performance.

Key Features:

• 4-inch mandrel bent T409 stainless steel tubing for maximum flow
• Filter-back design for simplified installation
• Single side exit configuration
• No muffler design for aggressive sound and unrestricted exhaust
• Corrosion-resistant construction for long-term durability
• Easy to clean stainless steel finish
• Backed by MBRP's 5-year warranty

Installation Notes:

This is a filter-back system, meaning it replaces the exhaust from the diesel particulate filter back to the exit point. Cutting of the OEM exhaust is required for installation. No exhaust tip is included with this system.

Performance Benefits:

By eliminating the restrictive factory muffler and utilizing larger 4-inch diameter tubing, this exhaust system significantly reduces backpressure. The result is improved throttle response, enhanced fuel efficiency, lower exhaust gas temperatures, and a deep, aggressive diesel exhaust note that announces your truck's presence.

Durability Considerations:

T409 stainless steel offers excellent resistance to penetrating rust and is ideal for moderate climates. While durable and easy to maintain, this material may show surface corrosion over time when exposed to heavy salt, winter road treatments, or coastal environments. Surface corrosion does not affect performance or structural integrity.
