Interested to know how much the install runs you if you don't mind sharing and also what they run into (how many manifold bolts they break off, lol). Oh and of course your before and after thoughts. Thanks for sharing!!
I paid a shop to do this all for me, though I had them install a full custom exhaust after the headers too. I believe the header install part of it was somewhere between $400-600. I know they had to drill out 3 (maybe 4) of the manifold bolts. Other than that I think that was the only problem they had while doing that part of the install.
Overall I've loved the way the truck runs and feels with the LT's and the exhaust I had done.
