sorry guys wasn't sure which forum I should post this in, but hopefully I'm in the right one. I have a 2010 Texas Edition Sierra with a 5.3 and was looking for some headers, I came across some I really liked but they were for the 2009. My question is aren't 2010s and 2009s the same truck same motors and everything? wouldn't I be able to fit those headers in my 10? http://www.summitracing.com/parts/PSM-72C2267/Application/?prefilter=0 <---- The headers I was looking at.
