Kooks and ARH are pretty much the only brands with consistent build and fitment quality.

We have a lot of experience with clients trying to save a buck and bringing us off brands to install. It's been such a problem that we have had to implement policies where the customer is advised they will pay for any additional labor due to fitment or quality issues from the parts they bring in. We also charge more for non name brand header installs simply because they take more work to "massage" them into place.

Trust me, it isn't worth it. 1 in 4 get lucky with good fitment. The other 3 spend JUST AS MUCH in the end as they would have by just buying ARH or Kooks up front and not having issues.
