I was under my car earlier while on the lift. Here's a few pics of the DC Sport headers clearing just fine. And with your year you shouldn't need the adapters that I need for my 91. Like A.S. Mentioned the headers should fit all the way to 05... So must of been the brand you tried.
Most manufacturers of headers might not know that their headers fit a auto simply because no one has confirmed with them. That doesn't mean it won't work.
