Company advertised bbk headers with an x-pipe and high flow cats for a 2011 Camaro. When the packaged arrived it did not contain the x-pipe, when i called the company they said it did not include the x-pipe. I attached the web pageof the advertisment. http://www.stage3motorsports.com/product/BBK40210/2010-2011-Camaro-SS-BBK-Long-Tube-Headers-X-Pipe-w-Cats---Ceramic.html?meta=GBASE&metacpg=BBK40210&utm_source=gbase&utm_medium=CPC&utm_content=&utm_campaign=BBK40210 read full review »
