SLP's PowerFlo® Stainless Steel Exhaust Systems improve the power and efficiency of your 2009-2013 Avalanche/Suburban/Yukon XL equipped with the 5.3L engine. They are available with dual outlets, unlike most other systems currently available. You can expect power increases of up to 12 horsepower at the wheels, depending on which engine you have, and a deep muscle car rumble with minimal interior cabin resonance.

These catalyst-back exhaust systems feature CNC-mandrel bent stainless steel tubing and a polished stainless steel, low restriction muffler that meets applicable state and federal drive-by noise standards. All systems include OEM-style hangers and clamps to fit factory attachment points and hardware. Our systems also include high quality polished stainless steel dual wall exhaust tips that exceed the quality of factory tips.

All necessary installation hardware and instructions are included for an easy, no cutting or drilling installation.

Use SLP's PowerFlo Single-Sided Exhaust System #31691 with our Sport Suspension Package.
