Stainless or ceramic coated? That's another poll. The header will be build with quality in mind. We don't want a piece of crap in our Cruiser. It is going to be ceramic coated with a minimum of 3/8" to 1/2" flange and of course a doughnut type gaskets.baxter650 said:Voted yes but the header would have to be made of either stainless or at least ceramic coated, have the dougnut style gasket at the collector or collectors with at least 3/8" thick flange at the head. Oh and under $600.oo
That is a good question that I also ask myself. According to the experts, it produces more HP, more fuel efficient and engine breaths easier, making the engine runs cooler.Romer said:Why would I want headers??
Maybe a dual exhaust system would be more beneficial for us? Anybody have this kind of setup?ginericfj80 said:Also, I think the restriction isn't at this point in the exhaust. The cats and then the tailpipes are the main restrictions. I from the downpipe back free exhaust would probably be cheaper and more beneficial to this engine.
cruiserdan, I think TRD is more interested in selling their supercharger. Headers, IMO, is a must if you have forced induction system.cruiserdan said:All of the above depenant on how good the original manifold design is. In the case of the 1FZ there is not much to gain over the original design. I spoke at length wilt a friend at TRD regarding 1FZ headers a few years ago. He told me that they looked into it but abandoned the project when they discovered there was very little, if any, gain available.

Brett06 said:dan, was trd considering production with stock exhaust or did they have another system in mind, because obviously with headers and toyotas original cats the gains wouldnt be good because the cats are so restrictive.
