Hi, I’ve got a off-road x pipe that I would like to install on my car but I want to make sure I have everything here before I dig in. I believe it’s a lethal off-road x pipe if that makes any difference and it’s going on a 11 gt. I’m missing the hardware and was wondering what size and grade bolts I need for connecting the xpipe to the stock manifolds. I did use the search feature but couldn’t find this info but I did learn that I should be able to use my old gaskets. I just need the info for the bolts.
