Easy to install. After installation, drove for 1 mile, brought into driveway and truck stalled. Check engine light on, P0161 code, was fine with stock exhaust. Failed inspection, obviously for light, magnaflow un-educated techs could not give me an answer, nothing posted on internet for my specific application. Yes I am frustrated, spent $600 on exhaust for nothing but headaches. Bought magnaflow 15842 for a 2004 Silverado, DONT DO IT.

Installation was much more difficult than implied; but a very good product. A deep mellow tone and slighty improved performance.
