Ok so i plan on getting headers for my 04 comp g, now ive read that speed daddys fit the same as 97-03 and i cant see why they wouldnt except the fact the placement of the cat is different. I need a cat but i dont know how it would be with everything stock. Like what problems and fabrication am i going to run into with these or is it just going to bolt right in? Any help would be apreciated befor i order them
