Thorley tri-y's on NNBS 4x4?
#11
I have the same ones on my '01 they went in very easy but mine is a 2wd and I had true duals built with high flow cats and spintech mufflers dumped damn thing is loud and I just put a cam in it. If my memory serves me correctly I think there was a card in the box that said they would fit on a 4wd as well, my only problem was when I bought them about a week later pacesetter came out a week later on summit racing and were really cheap for the ceramic ones and the tri-y's were the same price but I already had them on and could not return them. So I am going to deal with them for now and do somemore mods and see how she does, wish you the best, later.
