I have only one experience with these headers. My buddies wicked 300z. He has had ZERO issues with them. Anybody running this setup? They look like quality materials and I want cats. My car is currently stock and these mods are going on. Ported Trinity, twin 67TB, 2.4 pulley, boost a pump, 14 injectors, LFP heat exchanger/tank, billet idler pulley, JLT cold air and some tuning of course. I don't really care if they don't make the power others make, are they decent quality for less than half the price? I mean this setup is cheap and like I said, I don't care about maximum power. Thanks.
