does anyone know of a header for the si that doesnt eliminate the cat converter? im determined to stay in warranty, as as long as i keep my o2 sensor and cat converter i am good. dc seems to only make "race" header for offroad use only which deletes what i need to keep. feedback will help. thanks.

 

There is not a header out yet for the Si. Only the DC race header. There are some companies in the works for one.

 

Does anyone know when these are looking to be released? And what companies are looking to come out?
