question about kooks headers
hey guys i have a 2002 ws6 that i am building a 455 ci ls1 motor for. i am going with the kooks headers, 1-3/4 stepped to 1-7/8 with the 3 inch collector, i went to order the headers the other day and by accident i orderd the wrong ones, i orderd part number 6500-1RHS which are the race version with no air fittings. i ment to order part number 6505-1S which is the stepped headers, but they have the air fittings. besides the air fitting not being there, is there anything else different with these headers? can i get rid of the air system or does the car need it? i am just trying to get out of sending these back if i can help it, but if the car would run better with the air system then i will send them back and get the right ones. also if there is anything else different with the header itself being the race version, i will also send them back. thanks for the help
