Keep in mind that he is one of the best header builders on the country. His headers are built to extract every last bit of power, not a general one size fits all TTI. I have spoken to a few people that have his headers and they have told me they are worth every penny he gets for them. Again, these are not street car headers but competition headers. Have you ever looked into what a set of custom competition headers cost? Burns Stainless gets over $300 for stainless merge collectors.....that is for one...
