I could not figure out why they were promoting this product for my 2009 Silverado with a 5.3L. I read the reviews about how it corrected the oil loss and poor sound out of the dual exhaust. Both issues for me, prior to installing this device I lost 2 quarts of oil between oil changes and the dealer could not explain this on a vehicle with 66,000 miles! I have now gone 2,000 miles without oil loss. It sounds good and I see it does not go into 4 cylinder mode anymore. Pricey gave it 4 stars.
