i have an 02 rsx base model and was looking at the dc race header and the comptech race header, dc rh is 400 and comptech is 500, is there really a difference between the two? but for those who know about the 5zigen a-spec pro racer cat-back which race header do you guys think will work better w/this exhaust???

 

ill sell you my Jackson Racing Race Header

 

but for a base model right??? how much??
