PowerFlo™ Stainless Steel Exhaust Systems improve the power and efficiency of your 2009-11 Silverado/Sierra equipped with the 5.3L engine or 2009-10 Silverado/Sierra with a 6.0L. They are available with dual outlets, unlike most other systems currently available. You can expect power increases of up to 12 horsepower, depending on which engine you have, and a deep muscle car rumble with no interior cabin resonance.
