2009 Silverado 5.3L

I noticed an annoying exhaust note change when the AFM would kick in. The range device corrected that problem instantly. Product seems to well constructed of solid materials. I haven't had a chance to check any mileage changes but at this point I am satisfied to have the engine at full power. The truck is more responsive to the throttle.
I am glad that I found range for my 2013 5.3 silverado.
