Headers

If you haven't bought these yet, I would suggest avoiding them. I just received mine and I plan to send them back. I can't see anything but losing power with these. They are not a tuned design The shortest primary is about 11" and the longest is about 18". In addition, the length of the front and back y-pipe inputs are way different leading to wildly different lengths for the front and back banks and even each cylinder. In addition, the diameter is larger pretty much everywhere, which should lead to a loss of torque if you don't have any power adds that require more air flow and finally the workmanship is quite questionable. The finish is nice and the welds look good, but the flanges are cut all crooked and most importantly someone hand ground the area right at the exhaust port and on my back manifold, one port was 1.75" in diameter and another was 1.5" in diameter. This is the critical area where you need an anti-reversion effect. Aside from looks the only thing good I have to say about them is that the primaries are longer than the stock primaries which are so ridiculously short as to nearly not exist. Unless you want to design for like 10,000 rpm, long primaries are usually better.

Also, the design eliminates the stock catalytic converter, which means polluting or spending more money on a high flow converter (which I hear but have not verified, don't work as well).

You can disagree all you want, but I know I'm not putting these things on my wife's stock engine.

This is the way to go. Pricey. but u get what u pay for. ceramic coated. They will sell the headers only if u want. I have the whole package and its top notch. But tit deserves a S/C

^^ It's a big waste of $ if you're N/A. Like I said, headers will only benefit you if you're running big HP + boost.
