Have a '97 3RZ going into my '85 4Runner. I have the stock exhaust manifold from the donor, with no cracks - yet. I'm aware that it may not stay that way. I don't have a mini-header style manifold from a later model to look at, do they have the same dimensions as the earlier manifolds? If I have the muffler shop build my exhaust off the stock manifold, can I upgrade to the miniheader style later without modifying the rest of the exhaust again?
Also, I don't have the rest of the exhaust and my google-fu is failing me - what was the stock catalytic converter setup on a 97 manual trans Tacoma? Just a single cat with upstream and downstream sensors, right?
