Brand new here, I've had my Sierra for about 2 years but finally got around to joining GMTC! Still working on my truck but if anyone has advice it would be much appreciated! Check out my ride on CarDomain if you guys wanna see pictures! http://www.cardomain.com/ride/3824974/2010-gmc-sierra-1500-crew-cab-sle My truck: 2010 GMC Sierra Texas Edition 5.3L CAI SpinTech Muffler and a few other bits and pieces. My first question is...I'm looking for some decent headers for my truck, I've never worked with them before so I'm a complete newbie to it, what brands are good? if I was to get it for my truck which should I get?
