I just recently bought my Integra a week ago, came with full exhaust and intake and now im looking into buying a header, ive done a search and it really only brought up the DC Sport 4 2 1, 4-1, and the itr 4-1 header options. Are those my best choices? Also i heard that the itr header is really low, my car will be dropped soon.

 

DC Sports 4-1 is what I use, and it sits rather low, but not too low. If you're worried about clearance, just go with the 4-2-1.

 

If your search results only included 3 different headers, then you must have used it wrong. Searching for "integra header" returned 262 results in archived content and 7 more in recent content.

 

And here's a good one:
