Headers on the 2011 GMC
I just put a set of Kooks Long tube headers with their catted 'Y' tube on the GMC SWB. There is a serious difference in performance and sound. I think that this was definitely a good install. The factory system is so inefficient in comparison. I would have taken pics, but was running out of time.
