Best low cost option is a set of SC manufolds or the log style ones which are getting hard to find..good luck..oh of coarse you could make your own..:drive:
I tried LS 400 manifolds,sc400 manifolds and 2003 tundra manifolds the tundra manifolds are the easiest to use on the ifs they are very similar to the log style .
By the way the 2006 tundra manifolds are different than the 2003 manifolds .
My truck had a 1" body lift.
