    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.

    They better fit my fraternity brother just ordered those for his 2010. I'm putting them on for him and I took a look at his truck real quick to see any differences from my 2009, and there wasnt.so I don't see why they won't. I'm also switching to these headers and removing cats

    After you get them mounted let me know how you like them and any install issues. I may throw a set on my '11.

    I'm sure it most likely be a bit long but I'm sure the guys at my muffler shop will cut them to size for me

    What muffler do you plan to run? My buddy is gunna run cats a super 40s. He has to pass emissions still even though I warned him the headers might screw that up. When I switch to kooks from dynatech I'm going to keep my 10 series and no cats.
