if a 93 integra had a type r swap in it, which header would fit best, a 93 gs-r or a 99 itr? im looking to do a DC header, not stock.

EDIT: this is a buddys car. im workin on it. he wants a 4-1 header. he has a aftermarket traction bar in place of his stock crossmember so clearance isnt an issue. but they dont make a 4-1 header for a 92-93 integra because of that crossmember in the way. would i run into length issues if i use a 4-1 header for a itr? or 94+ gsr?
