Thanks for reviewing and I appreicate your input in advance.
At over 175,000 miles I just got my first cracked manifold a month ago. I have done a lot of readiing on headers in this forum and there is a lot of good information. My 2008 QX56 isn't a daily any longer but its value to me is...
I am looking to replace the stock headers/cats system on my 08 Armada for something more free flowing. I would like to get a new system with headers and cats so this isnt a delete. Just want something better. Any recommendations? Thanks!
I’ve browsed the forums and can’t seem to find a solid answer.
What I know now:
I can go with JBA, Doug thorley, or stillen headers? which ones are best and preferred as I didn’t see a huge price difference?
As of 1/1/20 the state of WA no longer does emissions checks. So don’t need cats.
